Even without the discount from AT&T, I still wouldn't want a Verizon iPhone. There are times when I go out of the country. Since most of the world uses GSM, I wouldn't want to be stuck with a phone that forces me to roam on world rates. At least with the iPhone on AT&T, I can do some software voodoo and unlock the phone.
BTW to the OP: Apple pretty much does what Steve Jobs tells them to do. If Steve Jobs is still pissed at Verizon for their advertisements attacking the iPhone, then you can forget a Verizon iPhone.
