But I did switch to AT&T from Verizon to get an iPhone. I'd switch back in a second if Verizon either got the iPhone or the Pre (assuming the Pre offers a user experience 90% as good as the iPhone -- which _appears_ very possible, maybe even likely -- and there are apps to replace the ones I use daily... I could use my iPod Touch for games if I really missed them).
If Verizon got both phones then, well, I'd have to see what the user experience was like on the Pre then make a decision. But if Sprint remains my only option for a Pre, no deal. The last rumors I heard were that their exclusivity was only 6 months... which makes me hopeful.
The thing that worries me most about the Pre experience is that as far as I know there is no virtual keyboard. A physical keyboard is a huge plus in my mind, but that means no keyboard available in landscape mode, which is kind of crummy.
