Graphix: that's a crazy high valuation for commute time. I generally use wage rates, which for a median income of 85,000 in Irvine is 42/hour. (and isn't that household income, too?) Even that's high, based on the actual choices people make - most people, or at least those who accept long commutes, would rather drive than work. With a fair valuation for time, your formula would favor the IE. What's missing, (and it's hard to do) is that it makes sense to accept a moderately smaller place here, which cuts back on the price differential at a loss in quality of life which is fairly low for many people.
I agree everybody *thinks* about the IE. We did, although we chose Orange. OC is better for people who value time, the IE for those who value space. A a lot of people bought in the IE to ride the equity elevatorn because they couldn't afford it here and that motivation should be gone for some time.
No Vas: An hour and a half from Chino Hills to Orange? It's bad, but I don't think it's *that* bad.
