So I made the upgrade from my 2.4 macbook to a 2.4 refurbished Macbook Pro. I'm very happy with the switch after reading some comments here on the forums.
For the macbook pro owners, did many of you upgrade to 4 GB of Ram? I mainly upgraded as I do a lot of work with Raw files in Aperture and Adobe Photoshop CS3 and found the macbook I had was too slow. (i had 2GB of Ram on my macbook).
I did some of the same work on my macbook pro and the speed in rendering was faster than my macbook. Will an extra 2 Gig of Ram, increase the speed significantly enough. I'm assuming that the 256 dedicated memory in the macbook pro handles alot of the rendering processes.
I upgraded the RAM on my MBP, but admit that I did it primarily because I have to use both the MacOSX and Windows XP Pro at the same time at work and really needed both systems to run smoothly. I did notice both working much more quickly after upgrading the RAM.
Check how much memory you are using after you have used your Macbook Pro for a long while doing what you normally do (or more). You can do this in activity monitor I believe. If you have alot of pageouts, then more memory will likely help.
