Personally, I was never a fan of indian cities when I travelled there. I'd like to live near a cheap beach town like Gokarna or this place near Mangalore : http://surfingindia.net/node/10 . That said there's likely no tech/startup culture out here, but hopefully much less smog/air quality issues.
Upvoted Pondicherry as that looks pretty promising too.
