I'm a bit more anti-apple than Shamus is, but I GOT the iPod. It made sense. I even own one because of two things: Capacity (I'm a music junkie and there were no comparably sized MP3 players at the time) and convenience (the number of accessories I could get that would fit well, like docking stations and cases).
I GOT the iPhone, too. I don't own one, and in fact, I'm nonplussed by my current phone lacking a keypad. But I get the iPhone and I get the following.
iPad? Not so much. Though I've got to admit, the idea of something larger does appeal to me on several levels, in no small part for the same reason of the DS example.
I could see this coming true, like others. Video Games aren't the only thing suffering from sequelitis.
