Hi, I need to upgrade to a macbook. I have been using a PowerBook G4 12" for a while now for website design/editing, graphic design, video editing, and a lot of just surfing the web/checking email. The problem is it just died and I think it's time I go for a MacBook. Which one would suit my needs? I have a very limited budget so I'm looking at going craigslist or something like that. There are some cheaper macbook pros that are intel core duo, but I think I need at least an intel core 2 duo. I'm open to any advice/suggestions. Thanks!!!
