The difference is that the iPad doesn't have the same constraints (namely available only on AT&T) that the iPhone had. Would Android really have had the same success it had if the iPhone was available on Verizon, Sprint & T-Mobile (and assuming Apple could keep up with the volume) from the start?
Anecdote: everyone I know who has an Android phone really wanted an iPhone but didn't want to leave Verizon. Now that the iPhone is on Verizon, most of those folks intend to switch to an iPhone once their contract is up.
(FTR I don't own an iPhone, iPad or an Android device)
That's in the US, what about the rest?
Yes, this is an honest question.

Being exclusive to AT&T was as much Apple's choice as Android's was to be on them all.
Yes I'm sure it impacts adoption rates, but we didn't see a huge rush to the Verizon iPhone. But, as you say, the real test won't come until people's contracts end over the next 2 years.
