17" iMac
From what I've read, the LCD shortage is hurting Apple badly with respect to meeting the demand for the new iMacs. Apple is missing a great opportunity right now because of supply problems. Apple has enjoyed fantastic publicity with the new iMac. If Apple supply had been able to meet demand, Apple would be generating even greater publicity that would lead to even greater market share.
If it were true that there is a ready supply of 17" LCD's that Apple could acquire right away, if I were Apple, depending upon unit cost and pricing position of course, I would consider rapidly adding an additional high-end iMac featuring a 17" LCD just so Apple could do a better job of meeting demand, selling the new iMac's while they're hot!
As for final pricing, I have no idea. Thus, I'm not emphatically advocating a 17" iMac in the short term. However, if Apple could maintain its margin targets with a 17" iMac that is less than $500 more than the current high-end 15" iMac, it may well be worth it.
Well, we'll see!
