So, as the title says, I'm considering trading in my 13" 2010 MBA (2 GB RAM/256 GB SSD) for an ultrabook (not so much out of choice, but money), and I'm looking for opinions. Let me explain the situation; I bought this MBA for university second hand off Gumtree (British version of Craiglist) almost a year ago for a really good price; £650. It came with almost a full years warranty, however, that is now running out (it runs out in August, with me going back to university in September). I asked in an Apple store near me if they could offer me a student discount on the Applecare extended warranty, and they said that the maximum they could do was 30% off. That would reduce the price from £200 to £140, however, I'm still unsure about spending £140 at this moment in time; £140 is quite a lot of money for a student. So, I'm thinking about selling this MBA, as I think I could get back the £650 I paid for it. This isn't because I don't like the MBA; its a perfect machine for my needs, but I just don't have a spare £140 to insure it, and the thought of something in it breaking and then having to fork out a repair bill that could be several hundreds is rather worrying. The ultra books I was looking at were the Lenovo u310 and the Sony Vaio T13; these both sell for about £650, the price I would (hopefully) sell my MBA for. They would have a 2 year warranty on them from the shop I would buy them from, and as an added bonus they are both Sandy/Ivy-Bridge laptops, albeit without a large SSD drive. Thoughts? I don't really want to get rid of my MBA, but I'm considering everything, and I'd appreciate an outside opinion.
