i know all of you beavertonians would disagree, but the quality of life, (traffic, bike friendliness, lack of urban sprawl) is much better in SE and NE. The commute is relatively flat, their are low traffic bike blvd's, and everyone and their mother is on a bike on the east side. The rent is comparable to beaverton, and there are actually walkable neighborhoods over here. yes you can commute over the hill, but that will be a pain in the rain. i burned through a pair of canti brakes on one descent last winter out of the hills.
dont live in a suburb!!!. it will complicate your life, make you drive more, and hasten our collective downward spiral. if you try to live in NW, it is expensive. but the entire East side has great deals to be had.
