I've had a Tungsten for a few days now:
+ Can it sync via iSync over bluetooth?
Yes, slower than the USB HotSync Cradle but still good.
+ Can one get/send e-mail wirelessly via a bluetooth connection to a Mac?
+ Can one surf wirelessly via a bluetooth connection to a Mac?
This is something people have been trying to get working, you have to drop into Terminal and use the pppd and natd commands to share the Net over PPP/BlueTooth. Unfortunately no one has got it working perfectly yet.
+ Is it easy to move files back and forth via a bluetooth connection to a Mac?
The HotSync software works flawlessly in Jaguar (10.2.2) very easy to use.
The TT is lightning fast, my Favourite software is SplashPhoto by
SplashData and Kinoma Video Player by

Really is a cool device and when the BlueTooth net access gets figured out it will rock. Have to sell my DLink BT adpater and get one with better range like the Belkin though
