With there now being several Windows 8 convertibles on the market, it’s hard to know which one you should go for. However, every now and again one device comes along and makes things a little tougher for you, as they come in two different sizes, such as the Lenovo IdeaPad Yoga 11, as there’s also a 13-inch version.

It’s great to have a choice between the two, but many of you will look at portability and battery life more, and so the Lenovo IdeaPad 11 performance and battery life will be very important to you.

A recent Lenovo IdeaPad Yoga 11 review has looked at many aspects of this device, and they have given us their take on those key areas we mentioned above. To keep things running smoothly is the 1.4GHz Tegra 3 processor, which works in conjunction with 2GB of RAM. There is also a 64GB SSD, which should be more than enough for your needs. We’ve seen in the past that other similar devices have crashed, but there were no such issues with the IdeaPad 11.

However, Engadget did notice several performance issues, and would often take a little longer to perform tasks. Boot up time is 30 seconds, which is much slower than other Atom-powered tablets.

These performance issues are due to measures to get as much from the battery as possible, which for those who cannot charge the battery on their IdeaPad Yoga 11 as often as they like is ideal. You can expect anywhere between 13- 16 hours of battery life, depending on what tasks you will be doing. While this is a bit of a gap, having any more than 10 hours is ideal for most situations.

If you would like to know more before you make a decision, then we have put a couple of Lenovo IdeaPad Yoga 11 video reviews below for you.

The Lenovo ThinkPad Helix release has been delayed for a little while now, but you’ll be happy to learn the company has narrowed the release window down by stating April will be the month the tablet come ultrabook will be made available.

It’s nice to see Lenovo finally offer us an official release date for their ThinkPad Helix via Twitter, even though we don’t have a specific date in April as yet. However, it does give you the chance to decide if this will be the device for you in a month certain to see other such devices released.

Lenovo say this is only the date for the US market, so other markets will have a while longer to wait, which is a little disappointing if you live in Europe or other parts of the world hoping to get their hands on the Windows 8 tablet with detachable keyboard.

We do know the Lenovo ThinkPad Helix price will be $1,499 and is expected to be ideal to work on AT&T’s LTE network. There is a concern in regards to the cost of this hybrid tablet, as it seems rather a lot for what you get, but we have to remember there are potential consumer and business users out there who believe this is just what they need.

However, we also thought the same with the Surface Pro, but sales have not been as good as Microsoft had hoped, although we have yet to see official sales figures. There are some people out there who believe the UK delay of the ThinkPad Helix is a great idea, as it gives another market the chance to beta test the device, much like the UK has done with the BlackBerry Z10.

With Lenovo showing off the new ThinkPad T431 Ultrabook it seems as though there are some issues with the new device, which potential buyers have expressed. This is not the news that Lenovo wanted to hear before they release their latest version of the ThinkPad, but with only a minor refresh on the offering what else did they expect?

So what Lenovo ThinkPad T431 problems have been articulated? Firstly there’s the design because it looks like something we would have expected around a decade ago. Another issue is with the resolution, because the T431 doesn’t seem to be that high, which seems like an oversight when you look at some of the other Ultrabooks on the market, such as this selection.

One Engadget reader has given three reasons why he will not be buying the Lenovo ThinkPad T431 when it is released in April, and that is because it does not have discrete graphics, touchscreen and a screen that can fold back completely.

However, the main issue is with the ThinkPad T431 price, because $949 is considered a lot when you see that certain specs are lacking, come on Intel HD Graphics is a bit of a joke. And before people tell you that there are MacBooks offering the same for a higher price, these laptops excel in other areas, such as their design for one.

The full specs can be found in the source above, but the ones that mater are the 2.7GHz Intel Core i5 CPU (i7 is available) 4GB of RAM, although this can be increased to 12GB.

Having already established that the Microsoft Surface Pro tablet suffers from a personality complex, it has still been getting some very positive reviews. Okay, so we know that not everything is great about the Pro, such as poor battery life, storage limitations and also the biggest issue, poor stock management since its release date.

However, the tablet/ulrabook still delivers, but how well does it stacks up against rival Windows 8 tablets? Thankfully we have located two video reviews that pits the Surface Pro against the Sony VAIO Duo 11 and the Lenovo ThinkPad Tablet 2. Both videos are touted as a comparison smackdown, but do you believe that these are the prefect devices to be compared to the Surface Pro?

In the first video some of the specs of the Surface Pro and the Sony VAIO Duo 11 are pretty similar, such as the Intel Core i5 processor and HD 4000 graphics. Both devices also make use of SSD, 4GB of RAM, and Windows 8 OS of course, but that’s where the similarities end, which are better explained in the first video review above.

The second video below looks at other aspects of the Surface Pro compared to the ThinkPad Tablet 2. Both come with a pen, but that’s about all they share in common, apart from the OS remember. While the Pro has greater performance, this has an adverse effect on battery life, so the Tablet 2 is the winner there.

We’ll let you take a look at both videos for you to decide which of the three are the best portable Windows 8 tablets. However, just remember that you not only have to take the specifications into consideration in this review, but also the price and what you actually need from such a device as well.

The announcement of the Lenovo Table PC will certainly confuse a few people, as they would assume that it’s a giant tablet, but Lenovo’s new Horizon 27-inch table PC is clearly designed not to be portable, one because of its size and secondly because of rumored its 2 hour battery life. However, we still have to admire what looks to be a great multiuser device that will run the Windows 8 operating system.

Even though the 27-inch Lenovo Table computer will run on Windows 8, this will need to be built on top of Lenovo’s custom user interface, which they have named Aura. We’re told that this UI is intuitive, but many aspects of the software will have that familiar Windows 8 look and feel.

The moment that you see this 27-inch Table PC in person you will think that it’s a monstrosity, and while it will be confined to your home or place of work, you can still pick it up and move it around, allowing for greater freedom than you get from your desktop PC, which one assumes is one of the key areas how Lenovo will market their Horizon 27-inch table PC.

We’re told that the new table PC will be ideal for gaming thanks to its size and easy focal point because it looks very much like a contemporary coffee table. For example, Lenovo will throw in a pair of plastic strikers, which will allow you to play the most up-to-date version of air hockey yet. You’ve been able to play such a game on the iPad, but this will be a whole new ball game on a device that is said to be 8 times the size of the iPad.

However, the Lenovo Horizon 27-inch table PC price will reflect on this, although $1,699 doesn’t seem that expensive when you consider the size difference. Instead of listing the main features of this device, which is on show at CES 2013, we thought it would be far better for you to watch a video preview of the Horizon 27 instead.

News had recently leaked about Lenovo’s touchscreen ThinkPad X1 laptop, which runs on Windows 8, but at the time the computer maker did not make any official announcement. Thankfully Lenovo has now made the ThinkPad X1 Carbon ultrabook available today and while it’s said to look very similar to the previous model, it’s the added benefit of W8 and touchscreen that has gained our interest.

It was obvious that more laptop makers were going to take advantage of the touch support that Windows 8 offers, but the jury is still out on how successful the operating system will be when compared to Windows 7. However, when you see the new ThinkPad X1 coming to the market the future does look bright, well apart from the dark and broody design of this latest laptop from the sponsors of the McLaren F1 team – if you follow the sport of course.

The Lenovo ThinkPad X1 Carbon Touch specs are much the same as its predecessor with its choice of Intel Core i5 and i7 processors, but it’s the addition of the 14-inch HD+ and 10-finger touch display that will set it apart from the previous model. Potential buyers have been asking if it’s about time that Lenovo got rid of the nub sandwiched in-between the keys on the keyboard because they associate it with much older laptops, but those who find it useful will argue that it helps to speed up their typing.

There seems to be some confusion over the ThinkPad X1 Carbon Touch price, because while it was first assumed that the new laptop would cost $1,399 upwards, Lenovo’s latest press release states that it will cost $1,499, that’s $100 more. You can see a slideshow video below and while it will be hard to see the differences from the previous model, they are there, just well hidden. We do worry that laptops are getting more expensive instead of getting cheaper, it seems that these devices will soon by out of reach of a huge percentage of potential buyers.

Specs which we can confirm include a 4.5-inch display which outputs at 720p, a single-core 32nm Intel Atom Z2460 (1.6GHz) processor, an 8 megapixel camera on the rear and WCDMA HSPA+, WiFi b/g/n, Bluetooth 3.0 and GPS connectivity. The K800 smartphones at CES 2012 all ran Android 2.3 Gingerbread and we’re not sure whether an update to Android 4.0 Ice Scream Sandwich is planned, all we do know is that Lenovo developers have heavily skinned the OS and bundled lots of pre-installed applications. Sometimes skinned’s versions of Android can adversely affect Android user friendliness, also third-party software can often be pretty lackluster, so we have some minor concerns about this aspect of the K800, that said the guys over at Engadget seemed to suggest that the skin didn’t take away from the Android-experience which millions of us now love.

Currently there is a big question-mark hovering over Intel Medfield performance and power consumption, sadly the sample at CES had no access to the Android market so benchmarking tools couldn’t be installed, however we are told that in SunSpider it slightly outperformed the Galaxy Nexus, if efficiency isn’t great we are glad to reveal that under the battery cover there’s a 1900mAh battery.

If you head over to LaptopMag’s blog you can see a brief hands-on video where we get to see the K800′s great multimedia capabilities, the single-core chip seems no slouch and when panning to different parts of a video there is no lag whatsoever. We also get to see a beautiful-looking gallery app where the user can see captured photos etc, sadly the video is less than two minutes long so there’s not much else on show.

In terms of design the K800 seems a little hit and miss, the soft comfortable finish is complemented by Engadget and so is its ‘noticeably light’ weight. On the top edge there’s a power button, speaker and 3.5mm jack, on the bottom edge there’s a microUSB port and a weird grill which almost looks like a vent for cooling (perhaps this is another speaker, we’re not sure what it is at present) you can see what we mean below.

As previously mentioned the Medfield processor is what people want to know more about, as the K800 is the ‘World’s first Intel-based smartphone’ we don’t yet know how it will compare to ARM, but we think that Mefield’s true potential will show once we see Medfield-based Android 4.0 and WP7 smartphones, also now that we have seen a single-core Intel processor for smartphones we’re sure that a multi-core offering isn’t too far away.

Sadly the K800 won’t arrive in the US, but it should hit China in Q2 2012, hopefully we will see a follow-up device in the near future with LTE connectivity, a multi-core Intel processor, a thinner design and a more up-to-date operating system – if so it could be a formidable smartphone.

Do you think Intel has a strong future in the smartphone market? Are you surprised to see Intel’s first-ever smartphone running Android rather than WP7 given Microsoft’s close relationship with Intel in the past? We sure are! You can see a full gallery of K800 photos here.

Motorola will be looking to launch their handset across both sides of the Atlantic while Lenovo will be focusing on a launch in China. Both smartphones will be running Google’s Android OS. Intel will be hoping to make an impact on the market as well as doing their best to compete with chipset rival company ARM, who are already enjoying success in the smartphone industry.

Intel’s Chief Executive Paul Ottelini is reported by The Telegraph to have stated that they already have ‘reference designs’ for tablets and phones which stick to standard features that are found in smartphones on the market today including fast graphics capabilities, speedy web browsing and a cameras of up to 16 megapixels, while emphasizing improved battery life. He also said that their relationship with Lenovo was just the beginning.

Both of the manufacturers’ smartphones will use the scaled down version of the processor Intel uses in its PCs known as the Intel Atom Chip. Motorola will be looking to launch in the months after the summer after gaining regulatory approval, while Lenovo’s device will be called the K800 and will launch in China during the second quarter of this year with the China Unicom network. The chip will also be used in one of Lenovo’s tablet devices.

Specs on both these smartphones are yet to be established but Intel will be hoping for an impressive start in the market in order to make an impact and to take on the might of other already well-established manufacturers in the same field. How much of an impact do you think Intel powered smartphones will have on the market?

What sets this TV aside from the other Google powered versions is that it will run the latest version of the OS as opposed to the earlier version Android Honeycomb. It will join LG’s model at CES along with a whole host of other smart TVs that will be debuting there from manufacturers such as Samsung and Sony.

According to the Telegraph’s reports this Lenovo TV will initially be launching in China with no details on anywhere else it may be making an appearance if it does. It comes equipped with a 5 megapixel webcam, SD card storage, 1GB RAM and will be run by a 1.5GHz Qualcomm Snapdragon processor. It will also be accompanied by a touchscreen remote control featuring an integrated microphone and voice control functions.

As the Telegraph also points out, CES looks set to have a theme that involves TVs like these that are a crossover of television and computers, accompanied with smartphone looking remote controls. In addition to this new smart TV, Lenovo are also reported to have announced a new tablet, the IdeaTab S2, a device similar to the Asus Transformer Prime. With all these innovative products that have been reported so far, CES is shaping up to be one heck of an event.

What are you most looking forward to at CES this year? What do you think of Lenovo’s Google TV?

The U400 is meant to offer the best of both worlds, as it has everything the U300 has, but adding an extra inch to the size of the display, separate graphics and an optical drive. For those of you who think that you are buying an Ultrabook here, then Engadget tries to let you down gently, saying that it is not.

The specs of the U400 are set in stone, so there is no way to bump the hardware up. What you get is an Intel Core i3-2330M with a speed of 2.2GHz, 4GB of RAM and a 500GB standard hard drive. However, you can opt for a bigger model with better specs, but once you have made your choice that’s it.

There are a number of departments where we are let down with the U400 compared to its smaller sibling, and that is a much bulkier design, shocking battery life, touchpad doesn’t live up to the hype and the performance is below-par. You are advised to wait and save your money and spend it more wisely, such as on Dell XPS 14z or the Sony VAIO SB. However, if you have your heart set on a Lenovo, then they do have far better options.

Below is a performance table, which Engadget has come up with, comparing it to a number of rival laptops in the U400 class.
