Not really - it's more like having 600 versions of the Volvo with each one just having different option packages. Trying to find which one has the options you want becomes annoying after a certain point and you just end up using one that you like that meets your needs.
As I've said repeatedly, I like the iPhone. The ONLY reason I didn't own one was AT&T, the ONLY reason. That said, now that I've had my Droid for some time and I have experience with the iPhone - I'm not so sure I can say that if Verizon had the iPhone and Droid at the same time, knowing what I know now, that I would have still picked the iPhone. Particularly so for ME, due to my use of Google applications.
This does not apply to what might be coming with the next gen iPhone (or Android phone for that matter).
