I want you to jabber me. And I want to be able to talk to you even if I'm away from my desk. For that reason, I hope my next mobile phone supports Jabber. Until then, I'll have to keep my AOL ID too, or at least the one I use on my mobile.
Speaking of IM on a mobile: I want a GSM mobile phone with a decent keyboard. One that supports the common PIM functions and gives me open access to my data. I want decent email, Jabber IM, and a web browser that doesn't suck.
The iPhone that ain't. The Sidekick it sort of is, except for the open access to my data part and Jabber. I currently get access to my data via XML-RPC (kind of cool) using the ID of an application that's been discontinued (definitely not cool).
Time will tell, I guess. Until then, inertia will keep me on my Sidekick II I suppose.
