Austin is alluring, but I can't seem to get my foot in the door at any of the big chipmakers in town. Not to be snarky, but I already have enough problems with power outages during hurricane season - ERCOT doesn't inspire much more confidence.
Why leave Florida just to move to Texas?
Texas can be pricey, but it has huge and diverse growing urban areas with a lot of job opportunities, where someplace like Miami is really cutthroat and very expensive.
Or you'd move if you like Mexican food more than Cuban and South American food.
