Well I am looking at the two different macbooks. And I see a couple differences, the ram on the alum macbook is DDR3 while on the white macbook its DDR2, the processor of the whitebook is slightly faster than the basic alum macbook. the whitebook has firewire alum macbook is lighter and has mutitouch. Now I looked up the difference between DDR2 and DDR3 ram, and well I saw that for now DDR3 is only a tad better than DDR2, but is much more expensive. Now I have no use for multitouch, well it doesn't interest me that much, and I love firewire and I like the white macbook's shell, although the aluminium one is better looking, I don't justify that for 300$ extra. Now I was thinking on upgrading the hard drive, and getting 4 gigs of ram on the white macbook. Will I see a notable speed difference if I use an alum macbook with 4 gigs of ram?? The processor is slower (2.0 vs 2.13) but the ram seems faster. This would be in regards to editing big photos (have a 100mb psd that I was working on yesterday, on my 2 year old macbook, it works but is really laggy (only 1 gig of ram too)). Also last question, I would love to fit in a 7200 rpm hard drive in the white macbook, as I think it would really speed it up, mostly when coming to edit big files (I also enjoy editing movies, and final cut on my current macbook is close to hell). Will these macbooks support 7200 rpm drives? And does it make a real difference? Thank you for the replies!
