@OP, do you require portability? The Apple Store has in the refurbished section a 21.5" iMac with the 3.06GHz processor. If portability isn't a need, get the iMac, save $250 against the MBP (which you can put into upgrades), get a much faster processor and a much bigger screen?
 
I really enjoy my SD slot, both my cameras use SD cards and I have always preferred using card readers to the camera cable. I was pretty excited to hear that the MBP had SD slots, and now that I have one, I use it all the time.
