Sony T1 in action on the web.

I am impressed, it is pretty fast.
I wonder if the PRS-950 has the same speed. Probably not.
Does any of the larger devices have the same speed as the T1?
Obviously the new Mirasol display will be the best, but that is at least a year before more devices use it. It is basically a 30 fps e-ink screen.
