Summary: I am running this laptop in an enterprise setting running arch linux and this machine has yet to fail me. Has awesome battery life although (at least on linux) the touchpad sucks. The backlit keyboard makes working in the dark a breeze.
Summary: This laptop gave me to understand that I would be able to immediately upgrade it to Windows 8. Even though the laptop has no optical drive, Windows 8 discs were included. I spent a lot of time, as did my son-in-law, on Lenovo's website trying to upgrade to 8 with no success.
Summary: Overall, I love this laptop Pros: 1.it is very fast 2.it is light, easy to carry everywhere 3.it is easy to use, I love the keyboard Cons: 1. battery life is not very long, I would say 3 hours probably. I would expect an ultra book to perform better. 2. noise of the fan. this is the major problem I don't like with this laptop. The noise is not loud but is easy to be triggered.
Summary: PROS: Super lightweight, fast and nice keyboard. CONS: battery life could be better. The aluminium coating shows every smudge, and is easily scratched. Does not come with Office -- it's in there, but you have to buy a key. Humbug!
