So let us review these new features and see what Apple has done behind the scenes. The current MacBook Air will last up to 5 hours at a push, but I have never managed to achieve that. The new 11-inch model is expected to offer 5 hours and 7 hours on the 13-inch model.

Both sizes are said to last up to 30 days when in standby – now this is something that would be worth upgrading for. Steve Jobs said that these new Air’s are very green – meaning that power consumption is kept to a minimum.

Connectivity wise things have been improved, but let us take a look at the 13.3-inch version, as this is the one that we already have some experience with. The current version has one USB port, Mini DisplayPort, Headphone Socket and a MagSafe. The new model has all of the above but offers an extra USB port and the much-needed addition of an SD Card reader.

Just those two extra features alone would make things a whole lot easier, as I would not have to carry an external card reader or my camera lead around with me. Are these or the other new features enough to make you purchase the new MacBook Air? For more details visit the Apple website.
