Today India's Tata Motors unveiled the $2,500 Tata Nano, a tiny four-door "People's Car." Some industry analysts say it could revolutionize Indian society the way the Ford Model T did in the United States 100 years ago. Unsurprisingly, Thomas Friedman has already warned Indians not to follow the first world and turn their country into one filled with even more traffic congestion and air pollution. We'll have to wait and see how many takers there are for the Nano, but meanwhile, here's a Nano vs. Model T comparison:

Introductory Price	$2,500	$850 (about $19,000 in 2006)
