Having lived in both San Antonio and Austin, I wouldn't actually mind much if San Antonio's tech scene caught up. I'm at the point I'm contemplating home ownership, and the fact that a decent house in Austin is starting to hit the $400k market while San Antonio's is literally half of that makes San Antonio very attractive nowadays, especially if they ever get shit together and build a rail between the cities. But my employment prospects are severely diminished there, particularly companies that offer the standard tech work environment and benefits.

And yes, before anyone says anything, I know that Austin is still relatively affordable compared to some of the other tech hubs, but its still its expense is still growing quickly.
