According to
Goodereader page turns will be handled by the processor now instead of in software which apparently is going to give us faster page turns and also less/no ghosting,oh and it's 3x more power efficient than the i.mx 6.
Seems to be a massive improvement all round,can't wait to see if the voyage 2 comes with this new cpu.
Last but not least it is also supposed to support upto 2048 x 1536 resolutions,that would make for a worthy kindle dx successor ...fingers crossed
