Use Google Maps for Subway Directions

As Rick pointed out a few months ago, Google Maps has slowly but surely been adding mass transit info from cities all over the world. Now, though, they've finally added the complete NYC subway and bus system, which means that HopStop now has some real competition in the public transportation department. While there isn't much difference between the sites when I'm surfing from home, the awesome Gmaps interface on my Blackberry means that I can now figure out all my subway routes on the fly.
