I currently use a iBook G4 and wanted to replace that with a new Macbook but I am not sure whether to get the base-line white model or the low-end Aluminum model? First off my brother has a late '07 2.2 GHz Macbook and usually when I encode DVD's I buy to the iTunes format I use his computer using the Handbrake application but usually I can only do that when he has nothing to do which is not that often so I would want something that would be as fast or close to the speed of his laptop which was the mid level laptop in late '07 and he did not upgrade the memory at all. Plus my iBook is fine for word processing and regular internet use by when watching streaming TV shows on Hulu becomes a pain since they become unwatchable so I wanted something fast enough to do that. I don't care about Firewire not being on the unibody Macbook since I never use it and I would also like something that has decent battery life since my iBook's battery will only last for about an hour if I am lucky. Having something that is cooler and a fan that is not as loud as my brother's '07 Macbook would be nice but are not musts. So I was wondering which Macbook would fit my requirements, the white base-line or the low end Aluminum Unibody?
