If you're in tech, Raleigh-Durham-Chapel Hill is a great place to be. We do get cold weather, but it's bike-able all year, really. We haven't had any ice in ~3 winters if I recall correctly (and when we get it, it doesn't stick around long). The downside is that we have very few bike lanes, and our drivers are not accustomed to cyclists (and can be downright hostile).

When we went to San Diego for a visit, we fell in love. Cyclists paradise based on what I saw. Flat rides if you want them, climbing if you want them, bike lanes everywhere. The problem is that the cost of living is probably 2x what it is in Raleigh-Durham. I think I like cold weather too much to move there, but the other major west coast cities are on our radar for long term places to live.
