I'd be sacrificing 2GB of ram and a Core i3 for a Core2Duo. I should still be able to play Star Trek Online using Windows XP and Boot Camp (which is the only thing I use in Windows). The thing is I just bought this Dell in February to make use of the HDMI cable in my classroom. I'm just mesmerized by the newer Macs. Do you think having Mac OS is worth the downgrade?
