The XDAII is great , buy one.
They are cheap now too. I've had mine for a year now and its been very reliable.
One hard reset only .... very few soft resets
Doesn't have full BT support for handsfree use, but is fine for answering calls.
Check it has the latest ROM version. Updates are downloadable and done via active sync
I wouldn't be without one, and will be tempted with the new version with built in WIFI.
Use it for TomTom (ta Jake!), MP3's and phone calls on the bike.
Then use the pocket office suite for work stuff. I also bought an expansion jacket with built in extra battery, CF slot and VGA out for Powerpoint presentations.
It can be set up to grab your emails automatically if you so desire and can handle multiple accounts. Web stuff is ok , but obviously the screens a little small.
Brodit do a great car kit and TomTom runs great and is a must have IMO
