I think there is a case in point when one talks of better infrastructure vis-a vis airports,metro etc in Delhi because Mumbai and Maharashtra has never been on the priority of those in power in Delhi when majority of tax collections to the centre go from Mumbai. A similar scenario in the IT capital,Bangalore. Btw many PEOPLE in USA know Bangalore more than Delhi or Mumbai. So why have companies still be in Mumbai or Bangalore is because of the mentality of the North. While you can invite businesses to set up by sops, to sustain them requires a psyche which only Mumbai gives. Can a woman walk freely and without fear at 3 am in Delhi? In Mumbai, no one bothers. And if Delhi has a better,swankier airport by 2010, wait till the new International airport starts in Navi Mumbai!
