Couple of newbie questions here. And yes, I know I should be able to make my own mind up! I have a 2010 june MBP which I use for web design and some light music making stuff. I actually spilt Apple juice on it last year but it was fine except the Trackpad doesn't work. Which is now a bit annoying. I do carry it around a bit and obviously a lighter laptop would be easier. So should I go and buy the new Air when it comes out? Taking into consideration I love the look of one and have been wanting one for ages now. I could repair the MBP but it may cost hundreds. Also, Im concerned about the Air's memory, is it ever really a problem?
