Minimum:
Ivy Bridge (incl. slight cpu bumps)
USB 3.0
Cheaper SSD options
Would be nice:
More RAM included
Better GPU (BTO or standard)
New wired backlit keyboard to take advantage of USB3's power, providing two extra fully-powered USB3 ports (not likely)
Don't care at all:
Retina screen
Chin or lack thereof
Any further reduction in thickness
Touch screen
iPad dock
I'm with you completely, save for the fact I'd put a gpu upgrade in my "minimum" wishes.
