I also had a Bionic, but quickly switched to the Razr. I love this phone. I have not had one problem with it. it has dual 1.2GHz processors instead of the dual 1 Ghzs in the Bionic. 1 gig of Ram, 16gig preinstlled SD card, also comes with a 16 gig SD card to be used in the SD slot. Expandable to 32gigs. Very snappy phone, very quick browsing and great radio/signal strengh. Great build quality ( like most Motorolas) and pretty good battery life with all things considered. ICS upgradable. Takes good photos( not OMG AWESOME!!! photos), but pretty good for a phone camera. 8MP rear camera. 1.3MP front camera. Either 10 or 12 different LED notification colors(which is why I reccomend the Light Flow app) In the event your phone "freezes" which mine has yet to do, you can perform a hard reboot by holding down the power button and volume down rocker for 10 seconds. Smart actions are very helpful and help conserve battery.
Overall a great phone. I chose the Razr over both the Rezound and Nexus, I felt that the razr was the best phone out of the 3. I know everyone won't agree, but that is my opinion.
Welcome to the wonderful world of razr.
