IMO it's a great phone! I gave my Bionic to my wife when I picked up a GNEX. Given the stable of phones out there, I think the Bionic is the real dark horse and will be 'the one' that, over time, may be the keeper. The Bionic has great radios, is built to last, lets you swap batteries, great screen (for my uses), and the Blur integration is tasteful and useful.
FYI, my wife needed a phone and I was curious about the GNEX. But in my experience (two weeks+ ownership), the build & the radios don't hold a candle to Moto (understandably given Moto's pedigree). Still, I'm giving the GNEX some time to settle in and if there's no joy, well, I'll swap phones with the wife.
Good luck.
