Lots of good pros/cons of New York mentioned in these comments, so just one thing to add I haven't seen mentioned: after 7 years living & working in Manhattan/Brooklyn, my network is saturated with people in a dozen different industries who all seem to have careers advancing at 2x speed of the people I know anywhere else. I consistently meet people in their late 20's and early 30's who are serious players in a wide variety of business and artistic endeavors. I don't have to go more than one degree of separation to find someone at the top of any field. I know less entrepreneurs here than in SV, but the cross-pollination in NYC is a big deal.
