MBP Downgraded
I'm sure Apple saves money by not having a removable battery, not having 400 FW, and (above all) not having an express slot (which will accommodate a SD reader as well as lots of other things) on the new MBP. Also by charging extra for a matte screen. My 2.5ghz pennryn non-unibody MBP has all these things and is, I think, a better value than the new unibodies, especially since I just bought it and it cost me 1/2 of what a new machine would cost. The advantage to the new machines are 1. magnetic latch, 2. take up to 8 gb RAM (mine will take 6), 3. longer battery life (which may actually be a disadvantage), and 4. graphics chip that apparently is slower but less susceptible to failure than the 8600.
