Is there truly that much difference between the MBP CPU either 2.53, 2.66 or the 2.8. I am looking at the 2.8 model only because it has both GPU's and 512MB instead of just 256MB. I had a early 2009 uMBP with the 2.53 that had the 512 it was great for everything until I had to start carrying it everyday, then I gave it to my older son who is in High School and studying Audio/Video and Photography. I am thinking of getting another in addition to my 2009 Mini, and my 2009 uMB 2.4
Each Machine has a special place although it looks like my other son will get the Mini, wife will get the uMB and I will get the new uMBP which one, not really sure.
I can not believe the only one with the 512 is the 2.8?
I looked at the older refurb models from Apple the 2.53 with the 512 VRAM is $1449 and the model with the 2.8CPU is $1699
