I had Razr M for a bit over a week and compared it at work to S3. The Razr was clearly faster, especially in real world browsing over 3G (don't get 4G at work). I also don't understand the decision to go with hardware home button. That just reminds me too much of iphone and Droid Charge. Motorola did that right following the Gnex example. I'm looking forward to seeing how HD performs.
