I need a laptop and have long been planning to buy a MacBook, but after seeing some older MBP's on eBay, I'm thinking of getting one because of it's large display and extra features. I don't have enough $$$ to buy a brand new one, and would probably be looking at one from early 2007. Would a 1.8 or 2.0GHz Core Duo be powerful enough for me? My main use would be for basic stuff like web browsing and office, but also website design, iLife, and some music production apps.
