There are 1-2 lone developers still updating this tab.
I have 2 myself but don't want to part with it even though i rarely use them anymore.
On the other hand, if all you need is a Pixel Qi screen, i just searched and found one in Amazon.com 575$+shipping..
maybe this can be hooked up to a Rasp-Pi board or used as a secondary monitor.
