I posted a similar thread under chit chat.
I can say that I have been disappointed with my new palm TX to the point that I would glady give it back to them if they'd refund my $600.
It is very buggy. So many people have trouble with wireless connections and it corrupting other software that I didn't even bother to set it up. I have had other troubles though with applications like Rhapsody, Itunes, and office documents. It's bad enough that I spend much more time trying to fix my TX then I do enjoying it.
Little to no improvement has been made on the basic applications like: task, memo, expense, calendar, etc. And given the amount of problems that plague the more advanced applications (the ones that command the steep asking price) I don't think it's worth the investment.
That is however the experience of only me. I'm a little disappointed that more of a thread didn't develop so that a more well rounded view could be used as a basis for rating this product and others like it.
