Here, you got a separate SIM even with Apple phones. It's just how it's done.
The only toy I remember not having a separate SIM card was Amazon Kindle (the e-ink reader), and that's because they try to hide that the SIM is even there (and it's kind of weird).
Sure, there was no other choice. I'm just saying that if anybody was going to introduce a universal SIM in the USA, I would expect it to be Apple, and for exactly the reasons I described :)
