Well, I'd have much more use for WiMAX than for PIM; but I can't say I need either. I'm probably going to get SERO, but WiMAX looks much more attractive, if not for waiting until it gets coverage...

So nobody needs WiMAX, because there's an existing two-device solution that provides the same eventual results... almost like a Palm and an N800, really.

So I'm inclined to reject the whole "need" term for both of these; they're both essentially integration details that add a little convenience, but don't provide any new functionality. And almost everyone who needs PIM is complaining that they still have to keep their old Palm... so they're not even having to spend extra money on the two-device solution.

BTW, I've used Google Docs; it does work OK in a pinch for me, though I wouldn't want to use it much. Rdesktop or VNC to OOo is much nicer, but not everyone can expose their machine to the internet conveniently.
