Even when the guy that runs the place (Steve Paine aka Chippy) recently updated the forum software (and consolidated it under the meetmobility.com url) he still left subforums for Nokia and each of the specific devices (even the 770!). While umpcportal is mainly focused on what he considered productivity devices, he until recently owned a N810 (tho largely unused since android happened, and he put it up for sale recently to fund new review devices).

He also runs meegonews.com, carrypad.com (tho most of the traffic there is by others right now, as he refocused his efforts on umpcportal and being a stay at home dad) and meetmobility.com.
