The Motorola Atrix 4G launched in the USA in Feb 2011 with Android 2.2 (eventually updated to 2.3). At the time of its launch, it packed some of the most powerful hardware in Android devices. Hardware specifications can be found on the Motorola Website. It received a few frowns in the Android Development community due to its locked Bootloader (it was later possible to unlock the Bootloader). It was considered unique due to its laptop dock accessory (Lapdock) which allowed it to power a laptop which loaded a custom linux environment capable of running desktop class Firefox browser amongst other features.
