I had sold myself on the MBP 17" w/ HD display but I did some math and saw the bottom end MBP plus a ACD 23" was almost exactly the same price. After giving each the fast 160 drive the difference was about $20 w/the ed discount. (any difference less than about $150 isn't enough to influence my decision) The 1st option gives me a slightly faster processor, more VRAM (I don't game) and an extra port. The 2nd option gives me more portability, the LED screen and extra real estate when at my desk. Am I missing something?
