So, I've been carrying it for over a week now, and I seriously dig this phone.http://xkcd.com/662/
Seriously, the screen is phenomenally crisp and renders beautifully. The performance of the phone is fine so far, and there are plenty of apps in the Market. I think my favorite might be Google Places Directory. It grabs your current location via GPS, and gives you a list of categories and gives you a list of places nearby. You can tell it to Navigate to it from current location and it'll give you verbal directions while it maps the route (or you can just view the map, or you can exit if you know the area but not specifically where something was, etc). Goodbye Garmin and TomTom, I'm sure someone, somewhere, will miss you.
There's a nifty app for the DC Metro system that shows in real time what trains are coming into the selected station, how many cars make up the train, and how many minutes from the station it is. Metro Center, Gallery Place, and L'Enfant Plaza are really cool to use to show this off, as they are the three major stations in the whole system. Those three stations are within a mile of each other, and between them, you can switch from from any line to any other line. Right now, Rosslyn, the Metro station about a block away, has an eight car orange line train east two minutes out, a six car blue line train east six minutes out, a six car orange line east train twelve minutes out, a six car blue line train south one minute out, a six car orange line train west nine minutes out, and a six car blue line south train thirteen minutes out (of course, those numbers have changed since I started typing this). It was free in the Market.
And of course, there are a bunch of games, news, weather, productivity, etc. apps all there too (for example, Documents to Go lets me read Word and Excel files with the free version, the pay version will let me edit them and adds PowerPoint and PDF (reading and editing) to the mix).
I'm very pleased so far.
