Hi to everyone, I've been reading all forums here for a long time, but finally I've decided to join because I have a very specific question I didn't find anywhere. Becoming a student this year I came to buying a notebook for my studies, and I didnt look for anything else except macs. I've found out that the most suitable one for me would be macbook air - I'm not a game-addicted person, neither movies fan as well. All i would use air for would be surfing the web, keeping some music, chatting and writing in iwork. But here's what really makes me puzzled: not that far ago I fell in love with the Left 4 Dead game by valve and it's the only thing which makes me keep windows on my imac, but I also wonder if there's any chance I'll succeed in launching this game on the Air? I mean I wont be sad if it won't work, but I would be very happy if I cold play in it at least with the lowest settings. And here's another problem coming: I'm getting about 1.2k dollars soon, but I live in Russia where even the Air rev.a(80g) is still cost from 1500$(!), but I found two great deals - I can either buy a rev.a wit hd for 1125 and further upgrade hd to 128gb ssd(i really found it - it's even 5mm thick zif!) or to get some more money and get rev.b for 1400$. But the problem is that it'll be very hard for me to get more money, so I just wonder if rev.a with ssd could launch L4d? Please don't tell me anything about 13 Pros or so on cause I really need the air's portability and I won't vitally need to play l4d on it. Thank you for all replies)))
