I just moved out here last week, and am enjoying it thus far. Seems to me like this is an area with a lot of money, and a lot of the commercial areas reflect that. Now, I've mostly stayed in the Tempe / Scottsdale / Chandler area, but across the board here, it seems pretty nice.
Other things I've noticed are that the people have been pretty friendly thus far, the traffic hasn't been bad, and it's hot, really, miserably hot.
