Pretty good discussion going on in that thread.
But to answer your question: nothing. They lost the market, there are no manufacturers besides samsung that really have a dog in the fight anymore. Google has pretty much given up and turned that focus over to Chromebooks. It’s unlikely Android tablets will ever have the same recognition as iPads.
Chromebooks on the other hand seem to be doing quite well. They also fill that need for a small screen, ultra portable touch interface unit like tablets…while also being more useful and the apps whether they are Chromebook apps or Web Apps are much more tailored to the OS (as opposed to mobile apps that don’t size correctly on big screens).
I think Chromebooks are really the answer here.
