Another way of looking at it is as the current evolution of the PDA. The Home Screen and way iOS operates even vaguely resembles the older Palm OS.
I use mine as a PDA/Music/Gaming device.
My phone is a 3G Nokia S40 candybar. I prefer having it separate for a few reasons:
- most phones I've tried have pretty crap sound quality, iPod is somewhat better.
- it's nice to be disconnected and _not_ have email/net/push everywhere. I have Opera Mini, if I do need to look something up.
- It's cheap compared to an equivalent converged device (iPhone). Both devices are relatively inexpensive compared to a smartphone with equivalent capabilities ($79 + $289), losing/breaking one or the other doesn't mean I'm $700+ out of pocket.
