So I was going to pick up the 15" MBP but figured I'd wait for MacWorld 09 to see what they announce. Sure enough they announced the 17" MBP. Some Comparisons: After student discount, 15" is $2,299 while the 17" is $2,599, that isn't much of a factor. 15" Weight and Dimensions (HxWxD): 5.5lbs 0.95 x 14.35 x 9.82 inches 17" Weight and Dimensions (HxWxD): 6.6lbs 0.98 x 15.47 x 10.51 inches Again, the difference seems very minor, as the 17" is only a pound heavier, just over an inch wider and just under an inch deeper. Specs aside, and considering only portability, is there any legitimate reason (other than price) NOT to get the 17"? Does anyone know the dimensions of the previous generation 17" MBP? Seems like it would have been a lot larger from what I remember.
