Thinking of switching from windows laptop to MacBook. Have a few questions

I have a 2007 MacBook. I use it everyday, it's been on many trips, and I have no stains or cracking.

I can't speak for the newer MacBooks, but mine ran fine with 2 GB ram. I did however upgrade to 4. (The upgrade I REALLY noticed was an SSD.)

I used pc's for over 20 years before I bought my Mac. I've been extremely happy with the Mac and OSX.

Good luck with your decision.

it shouldn't stain, it's just plastic, and it also shouldn't crack unless something accidental occurs like dropping it or whatever. the build quality of apple products is exceptional. whether or not 2gb runs smoothly depends on how you will be using it. keep in mind that the 320m is going to take 256mb as shared vram, so essentially you'll only have 1.75gb. that's more than enough to do everyday tasks, but if you are going to be using it for more than that then you should upgrade your ram (aftermarket to save $).

do NOT buy a macbook at this moment! Wait for july, it might get updated!! and if it doesn't, the macbook air will probably take its place. (or the macbook pro 13").
The thing is, the white macbook model they're selling right now as "new" is more than 1,5 year old! you should better buy a macbook pro 13" or wait for the updates in july
