I am planning to buy a MacBook, but I'm not sure if I should gat a MacBook Pro, or just the MacBook. The most I will do is 1 xcode project, a few YouTube Videos, PhotoShop CS5, and minor video editing (iMovie). When I do this on my MacBook I have now (I think a 2008 model), I use most of my memory and CPU. I also want it to be fast, not just work. Is the Pro worth the extra 200 bucks for a little bit of a speed increase?
