We just heard from JBMM about this cool concept device by AlphaUI.
It seems to be a keyboard strapped to the back of the device. A technology called BackTyping. But see for yourself.
Apparently they are about to launch a Beta test of their hardware for the A5IT.
So if you live anywhere near Paris or Brussels. (They won’t ship by mail and I can’t justify the costs flying there! While I want this soo bad to try it with all our Froyo/MeeGo/Angstrom images!)
