Thankyou for putting me onto this. I have far too many keyboards as it is (2 dinovo edges, HP mini bluetooth, Microsoft wired ergonomic, and dinovo mini) now I'm down to one device that uses a keyboard, but the device switching looks like reason enough to sell one of the edges. If only it had a touch pad like the edge (it might be small, but having used it for 5 years, the size of the sp3 touch pad should not be an issue )I love my K810. Had it for over a year using it every day and I don't think I've charged it twice in the whole time.
