Hard to argue with free. As in, "why pay $90 for GPS navigation apps for your iPhone when you can get it free from Google"? Google Introduces Free GPS Navigation for Android 2.0. Google Maps is optimized for online use (so not good if you're traveling and don't want to be raped by your provider for data transfer), and do voice input (as in "navigate to 1234 main street, Vancouver", or as I like to put it, "HOLY CRAP AWESOME!"), as well as have all the goodness that Google Maps has with spelling corrections, transit/walking/driving, traffic data, etc. Video included in the post is great stuff.

I won't lie, this makes me want to try out an Android 2.0 device...
