I live in Miami, and the tech scene here is...small, and there's not really a lot of potential for moving up/around.

There are some good employers with a startup mindset like Ultimate Software (payroll/HR software) who pay well, but, the pay is marginal for everyone else. ADT and Office Depot are in the Boca Raton area (great if you've got Hadoop skills or retail experience), but, I haven't heard that people are paid above the average around here.

I live in Downtown Miami (and work from home), so, I can't comment on commute:
