Damn that is pretty good. The Domain is like it's own little high end community surrounded by all the high end stores, and keeps expanding every year. Was always curious what it would be like to live there.
Honestly if you are looking for your own place to live, depending on how far away work is, it's often a lot better to live outside the city. I live just on the southern edge of Round Rock and the general cost of living is much lower then when I lived in North Austin. I pay less on the mortgage to my three bedroom house then some apartment complexes were asking in rent for a small two bedroom in Austin.
Though this works for me because I work in North Austin, so my commute is only 20 minutes (less if I take the Mopac toll way), where traffic would likely make any commute a nightmare if you have to go near or past Downtown Austin.
