I'm returning mine. Really bummed because I got the great deal at BB ($239 and a $75 credit from Sprint on my account for renewing). I'm coming from a Palm 700wx, and while I agree that the Treo is much older hardware, it is so much more useful for me. The exposed keyboard (I am a BlackBerry user as well so no problem with small keys) plus the hard buttons makes it so much more functional.

A few more early observations:
1) the touch pro gets annoyingly warm after some use
2) once I turned it off with the battery around 50% and came back to it after a few hours and the battery had run dry
3) I too noticed that constant buzzing feedback coming from the speaker
4) the screen is too "slick", meaning that with the stylus I need to press close to a 90 degree angle else it slips
5) screen presses require more pressure to register than other smartphones
6) short stylus is lame compared to a full size metal one
7) d-pad is poorly designed, meaning where you press needs to be approximate (since there are no hard buttons on the dpad), leading to occasional unresponsive behavior

my two biggest uses are Slingplayer and Opera Mini, and both perform better on the Treo. I regularly get 29fps with the albeit smaller screen on the Treo but can't achieve similar performance with the same settings on the Touch Pro.

Opera Mini + Esmertec JBED shows more on the screen (after zooming in of course) than the Treo but it is far less usable without dedicated scroll keys (on the Treo I use the numerics to scroll up/down/left/right).

So I will probably play with it for a few more days then back to BB it goes. I'm not thrilled going back to the Treo but I guess I will wait some more. I always felt the 800w is not much of an upgrade and I guess the Touch Pro form factor is not for me either.
