Am I the only one who feels like there's (almost) no talk about Mac hardware upgrades at the expo? I want to know how likely it is to see an upgraded iMac at the expo. And more importantly: What kind of upgrades can we expect? Where are the rumors? All I see is iPod & iPhone (and I'll probably buy both ), but what about the machines? P.S.: I hope you guys don't kill me for asking. Mitra.
