I guess I'm using a different definition of "general purpose computer" - IMO, it's defined not so much by the device design, but rather what people do with it.

I guess I'm using a different definition of "general purpose computer" - IMO, it's defined not so much by the device design, but rather what people do with it. It's possible to do almost everything you can do with a normal computer on an iOS device, and for many people, it's their primary or only computing device, which I think makes it sufficiently "general purpose". (There's also the other definition of "general purpose", which is that you can install your own OS on it and have full control over what software you run. I think Apple should allow that too, but that's sort of a different issue).
