People are missing the point that there isn't an actual sim card now, that you don't get the "apple" convenience AND the ability to pop in some random carrier's. It's convenience at the cost of flexibility.
That's actually pretty terrible. I was thinking it was a SIM card with some Apple-designed logic in it. Not a baked-in SIM card. I wasn't really considering the device but now it's out of the question. Hopefully they don't do the same thing to their phones.
