Other features I'm looking for are:
*Screen big enough to read & reply to emails, also skim through pdf files looking for a key point — I don't want an ereader, but I'll often be in a seminar and want to look something up quickly.
*Ability to use WiFi instead of data plan, and smart enough to use it when one of my preferred networks is available without me telling it to.
*can tether my laptop if needed via either wifi or bluetooth
*Can fit in a reasonable size mens pants pocket, and is robust enough that the screen won't crack when I sit down (had an iPaq do this once). I am open to using a holster, but I worry about snagging on things and also exposure to the elements when biking to work.
*decent battery life
*GPS would be nice while travelling on conferences but not essential, ditto a decent camera
*full on web browser that can handle things like TiddlyWiki would be very useful as well
Does such a beast exist? Has anyone used one and if so what do you think? Bonus points if you know if I can use it with Rogers (Canadian wireless provider used by my workplace)."
