Atrix = shit software, slower CPU, MotoBlur, no updates, old version of Android (10 months old), locked AND encrypted bootloader, PenTile screen looks like shit, extremely mediocre camera.
Why would you ever do that on yourself when the SGS II does everything flawlessly?
And how is this even a contest, the Atrix is not available in the countries where the SGS II is launching.
As usual, Motorola was first to announce, last to market.
