I booted the QSB with the microSD that comes with the package. The board boots up fine. However the general board performance seems to be really slow. Click on icons get really slow response. At first I thought it was the mouse not responsive then after a minute or so 5~6 windows of the same app popped up. That seems to indicate the system is too slow to the user input. Also moving a window by dragging the title bar leaves a lot ghost image on the screen. There is a youtube video on the net showing the QSB and the demostrator also experience the similar problem. For a 1GHz processor with 1GB RAM and GPU with 2D/3D acceleration I would expect better perforamce than what I have seen. Any comments?
