Currently, I have a 2.4ghz Macbook. It's in great shape and has served me well. I have an opportunity to by a 15" MacBook Pro, but it's an older model... the A1286, also with a 2.4ghz processor. I really like the unibody, and I like the slightly bigger machine... but I really, really like that it should have a back lite keyboard. I can buy the used Pro for $800. I should be able to recover a lot of that by selling off my white book and the extra NIB battery I have for it. Think I'd really be upgrading, or just pushing stuff around for no reason?
