Yes, I relocated to the Ann Arbor area. There is actually a fair amount of tech here both in Ann Arbor, in Detroit, and in Novi and similar surrounding suburbs of Detroit.

I work remote for a SF Bay Area startup though so I haven't explored local employment options too much. There is a big consulting company however the area they cover is large so you could end up on a project that has you doing a 1.5 hour commute (one way) for 6-18 months.

The research triangle area is attractive to me too. I just haven't had the time to make a trip there to get a feel for it. The housing is slightly more affordable than Ann Arbor although it's pretty close (light years better than Bay Area of course).
