Portland is awesome. Before you move, find out the areas that are hard to receive OTA signals as Portland is very hilly. I am fortunate that I live in the Williamette Valley where it is flat and have no problems with any of our local digital signals.
The last station to go digital that we are waiting on is WB, should be up hopefully by March. FOX is now broadcasting in 16:9 480p and our PBS (OPB) has a continuous HD loop as well as the Smart Travels and other awesome HD shows that have been on PBS.
