I got my T3 on Friday night. Except for a few glitches, it’s great. Its main features are Bluetooth and its expandable screen (software Graffiti area). Below the Graffiti area (or just at the bottom of the screen when there is none), you have little helpful icons: home, find, menu (the buttons in the GA); Clock with tap to useful info/settings, Bluetooth button for net and BT connections; write-anywhere,screen rotate, and GA toggler. I’ve found these buttons to be extremely useful in getting to various functions quickly. So far I’ve installed some DIAs (Dynamic Input area) skins, font changers (to have stuff show up in Times) to customize the display. I grabbed PocketTunes, the more popular (apparently) mp3 player, which is skinnable, so now it looks likes iTunes. 
Also, I was having trouble with the web browsers, so I used an included app called Phone Link to set up the connections to my phone. It worked, though it picks things differently than I would (it set up a LAN connection to my phone rather than a ‘Phone’ connection…*shrug*)
Glitches (dunno if these are Palm’s fault):
- When using Drag’N'Tooth, the Palm doesn’t disconnect by itself. I have to power cuycle it in order for it to let me accept it.
- Removing/inserting SD cards causes fatal error (my cards might be borked)
UPDATE: the Disconnect seems to be an issue with D’n'T, and after a hard reset, the SD card thing has gone away.
