Looking at the new MacBook Air to replace my 12" Powerbook. I like small laptops. It's a flaw, I know. Regardless, this thread is not about which laptop to choose. If I went with a MacBook Air, I am constrained to 2GB RAM. I currently run Fusion w. XP on my Alu iMac and it runs like a champ, but that beast is maxed out to 4GB. Anyone running this setup with 2GB? What about Vista (I know it's a RAM hog, but I've only ever used it on a Dell with 2GB). The kind of things I'd want to do are surfing IE-only websites and MS Office type tasks with custom work macros.
