Hi and I need some advice... At present I have a going on 3 year old pre unibody 17" 2.4ghz 4 GB Ram and 160 7600 Macbook. Its been sent into Apple a few times over the past year+, replaced the logic board, screen, battery, etc... so its 'almost' new, and still 5 months on the Apple care. Have been bumping on the HD space for some time, so an upgrade is needed there (if I keep it). Is the new MacBook Pro that much faster? Thinking of the 17" again and the 500 7600 is a no brainer with the thought of an SDD at some time and moving the 500GB to the optical bay. The option of 8GB of RAM sounds useful - see next paragraph. I'm doing the usual work that the older does fine, but am getting into using Aperture and larger (30MB) RAW photo files. Advice, thoughts, and thanks for them.
