Apparently I am also hearing that this model has an added bonus of going into "Battery Saving Mode', not sure if it is true, can someone confirm. While in that mode, apparently, battery life is really increased. I have still not seen this device in the wild.
Rumour and Speculation at this point. I'll try to find some confirmation. http://www.youtube.com/watch?v=DV2_V...layer_embedded
Seems to be going to all devices 7.1.x.xxx
