Mac versu PC,{snicker,snicker}

[Ron99]

Once you go Mac, you never go back

Seriously though, I have used them all; Windows, Mac, various flavours of Unix and the Mac is the best integrated and user friendly. Also, aside from the lack of included bloatware you get a bunch of really useful free apps.

2 Gigs is no big deal. Memory is cheap and easy to install. Just don't buy it from Apple at their overinflated prices.
