I currently have a custom built PC thats a tad outdated (2.4Ghz 939 Dual Core, 2GB DDR400, 500Gbs in Raid0, and my recent upgrade a HD2900PRO). This is my main machine for college/studying, surfing the web, listening to music, watching videos, and gaming. I did have a Macbook about a year ago that I bought for college but I eventually sold it because I didn't seem to use it as much as I thought I would. Now however Im thinking of totally ditching windows and converting over to os x completely. I did love the os interface, apple hardware, and everything about it. It was so much better using the macbook for my daily computer needs except whenever I got the urge to game a little. The games I usually will play are Steam games (ie - CSS, TF2, etc..), COD4, UT3, WoW. I found myself more on my desktop PC when I'd rather be on the Macbook even when I was not gaming. I guess I didn't like switching back and forth between computers/OS. I just want one main machine for all my needs. Now I am a bit tired and fed up with windows and my machine that takes up a lot of desk space creating a lot of noise from all its fans. My dilemma is whether I should get rid of my desktop all together and get a Macbook Pro or even a iMac since those machines should be able to handle the games I enjoy right?. OR Keep my desktop for gaming and go the ultra portable way with the Air?
