Looking at the Buying a MacBook versus MacBook Pro on the MacRumors website: http://guides.macrumors.com/Buying_a...us_MacBook_Pro There is a difference of $1,200 between the high-end MB and the high-end MBP. What the evident differences are: 1) 0.24 GHz in processor clock speed (2.16 vs. 2.4) 2) 1 GB RAM (1 vs. 2) 3) 2.1" more screen space (13.3" vs. 15.4") 4) 40 GB more hard drive space (120 vs. 160) 5) improved GPU 6) other, non-performance-based differences The question I have is: are these differences worth the MBP price? Two high-end MBs ($2,600) are almost the same price as one high-end MBP ($2,500). I consider the RAM and the hard drive space to be somewhat unimportant. You can upgrade those for around $200 or so, making the difference between configurations around $1,000. What I would like to know is 1) Whether the clock speed and additional screen space alone justifies the $1,000 price difference, 2) Whether the much better GPU must be included to justify the price difference, or 3) Whether none of these enhancements justify the price difference? Your thoughtful opinion is appreciated.
