I have a dilemma here; I absolutely love my MacBook Air; it's an awesome computer, it's pretty fast, and the battery life is terrific. Problem is recently I've been running out of RAM on this computer and there isn't a way I can upgrade it. When it starts swapping, I can feel the increase latency. It also gets terribly hot and there is nothing I can do about that either. On the other hand, I have a Thinkpad X200 Tablet coming in (it's being built). It's faster than the MacBook Air in some ways, has an ever longer battery life, its got a gorgeous IPS panel with multitouch and pen capabilities, has more RAM. I love Windows 7, and I have found myself using that more now than OS X which is scary. Which computer should I stick with? I have never used a X200, but I loved the X60 which was a great computer. I'm sure this one is better. I'm pretty solid with the Air minus the fact that I keep needing more RAM than 2GB. I obviously can't keep both. Just as a background to why I even have an X200 coming in: Old X60 got dropped in a pool, Lenovo told me they didn't want to fix it and would just send me the current maxed out X200 instead.
