Macsavvy Friends, I'm hoping to buy a new MacBook in the next couple of days. Having never bought a Mac, I have a couple of questions that I'd love to hear people's opinions on. Let me say, first of all, that for the last 3 years I've been using a Dell with 1.30 pentium, 256 mb of ram, and 40 gb, so anything new that I get will be a huge improvement, i'm sure. I'm hoping to buy the 1.83 ghz macbook, and my primary question is how significant the difference is between having 1 and 2 gigs of ram-I've read around enough to know that I don't want the 512mb. I'm a student, so I'll primarily be using the computer for Microsoft Office, web browsing, and some media stuff, but nothing so fancy as heavy duty video/photo-editing. I'm on a budget, but I also know that a computer is an investment, so I'm curious if the 1gb of ram will be enough for me, and what I'll miss out on if I only get 1gb. Thanks for any advice you might have.
