Nope but I use the TREO 600 and its a kick *** machine. You should definitely check it out. The geek who runs our IT swears by it and he has gone through them all
I have come to accept the fact that I need to get something to check e-mail when I'm out of the office. Will either the Treo or the Blackberry allow me to do that without setting up some high tech deal through my firm? I'm the only one that needs it. Actually, my partner also needs it, but he's rebelling.
