Wolfram Alpha is pretty good for things like this, though the data is a bit stale: http://www.wolframalpha.com/input/?i=computer+software+appli...
I've tried for New York, San Francisco (both terrible), Austin, Dallas (pretty close), Boston, St. Louis, Denver (also pretty close) and Seattle among others and Houston beats them all.
But I have a friend that has been in Houston since he went to Rice and he swears by it. His girlfriend even lives here in Austin and we can't seem to convince him to move back.
I love Austin, but I think Houston is big enough that you can find your people.
This may be indicative of something else entirely.
