I think both sides have valid cases. I was previously with at&t (Cingular) and switched after like 7 months (didn't pay the cancellation fee). I had the worse experience ever and will never go back. So I believe it is unfair for the iPhone to be locked to att&t because "i'll die before going back"
I am forced to boycott by association, not because of that Working Assets propaganda.
As for the apps situation, although there are a large number of folks that will install and use these apps, the mainstream majority are purchasing it because its a Apple iPod type product. They will use it to talk, play music and surf.
Most will never even use the basic functions that the iPhone already offers, like that stock portfolio garbage. most will never even use the bluetooth, except maybe to hookup their ear piece (if it can even be used for anything else).
