The latency of pen/pencil sketches on Boox devices is near nonexistent, similar to or better than iPad latency but theirs is handled in the display controller hardware without traveling through the OS interrupt handler stack. It's really good. With their scratchy matte screen protector and a LAMY body around the wacom nib, it's really like writing on paper.

If DC can pull something like that off, I'll be really impressed!
