We really liked Motorola's Droid RAZR. It was crazy-thin, water-tight, and had a form factor we'd never seen. Too bad its battery life was sub-awesome. The RAZR MAXX is a little thicker, but it should keep you untethered from outlets 'till bedtime.
21 hours on a single charge: That's the promise of the Droid Razr Maxx. 21 hours of what? We do not know, but if it's 21 hours of video streaming I will wear a dress to my next CES press conference. Your mileage may vary, basically. The original Droid RAZR is the world's thinnest smartphone at just 7.1mm. The MAXX is 9mm, so it loses that super-duper thinness, but it's certainly not chubby. It's got 32GB of storage, too!
Oh, and you can also now get an original Droid RAZR in purple. Because, y'know... purple is the color of royalty. Or was. In ancient Phoenicia. That one has 16 GB on-board memory.
