neat :) 

i have seen better performance on similarly (and worse) spec'd ARM devices, 
however, so i'm wondering what might be causing some of the issues seen in the 
video. one thing i did notice was when creating a new activity there were 
graphical glitches that look to be driver related?

there are also visible artifacts on e.g. the panel shadow which is rendered as 
a black block or when applications are started (similar atrifact as when 
creating an activity).

it's a very interesting start, but sorting out which problems are at the OS 
layer and which are due to PA itself would be very helpful to knowing where we 
need to focus attention (as we can improve the latter, but do less about the 
former)

keep in mind that the shell itself is still using QML1 which does not have the 
full opengl rendering system that QML2 does. i suspect (based on playing with 
it :) that when we switch to QML2, we'll see a much more useful and visible 
jump in performance with GLES accel HW. one more reason to push forward to Qt5
