Love my Atrix HD... but not sure how this is news... 🙁
I would still go with the Atrix HD over the Samsung Galaxy SIII even if both were the same price.
The UI on the Atrix (and Motorola in general) is the most pure version of the Android without being a Nexus phone. The construction, the bright screen, the non-fingerprint-magnet body, the speaker and audio quality makes it my choice... the camera is crappy... but its a camera-phone camera... oh well.
