Of course, the navigation aspect of Google Maps is nice. I have version 3.413 because the last time I updated it the search result info screen had been mangled so badly the program became a real pain to use. The intensive therapy I had to undergo to get over the horror has made it difficult to remember the details, but I remember that when I would search the map for, say, hotels and select one, the info screen that came up had nothing of use when it opened. The only on screen option was "Buzz", which I know some people might use once or twice a week, but to get the other options, like Navigate, and Get Directions, etc, I had to swipe to an off screen page. Thank god for Xanax. And thank god I was able to roll back to the good version.
Also, check out the labs options in the More section of the map menu. You can put an on screen button for My Location, Layers, etc., as well as a scale bar and other cool things. Don't know if that's exclusive to 2.1.
Also, tapping the home key on the home screen brings up the seven home thumbnails, same as pinching. I haven't seen anybody mention that, and pinching is a real pain with one hand.
