I looked at a recent email I got from PalmOne and was happy to see this:

Have a moment?
We'd love to hear your comments on the Treo 650 smartphone. Your feedback on a short questionnaire will help us improve our site, shopping experience and products.
Go to questionnaire: http://www.zoomerang.com/survey.zgi?p=WEB223WSXKUCSN
I thought, great, I can finally channel my energy and let them know about the egregious bugs I can replicate on this device!

Too bad clicking the link takes you nowhere... the "survey has closed."

So, is there an official channel that a power user can report bugs in the Treo 650 to?
