Review: Motorola Atrix 4G
Bluetooth
The Atrix 4G supports both mono and stereo Bluetooth headsets. I was able to pair it successfully with a number of different devices, including two PCs and various headsets. Call quality was excellent through a mono headset. Music sounded good through stereo Bluetooth headphones, though it wasn't quite up to par with the mono headset.
Clock
A quick press of the lock key lights up the screen and shows the time nice and large. The time is nearly always visible in the top info bar. There are so many clocks and clock skins you can download from the Android Market, you can really configure the home screen clock in pretty much any way you like. The clock in the info bar can't be customized or changed.
GPS
Both AT&T Navigator and Google Maps 5.0 are included on the Atrix 4G. AT&T's navigation software, which costs $10 per month, does a fine job of delivering turn-by-turn, voice-guided directions. So does Google Maps, but it is free.
