What I would like to see and have - a #Raspberry-Pi device with screen, wifi adapter and 3d printed case. That would be a nice and cheap platform for development of free mobile technologies. As a start point, we may port there #mer, (#meego) #nemomobile, #shr, #qtmoko.
And not having a #gsm module may be advantageous - we may start to communicate with each other more via #jabber #xmpp by using encription and our own servers, whether by doing voice and video calls via #internet or by writing chat messages and emails instead of expensive and overpriced sms messages.
After all, we do not need #carriers, we need just #wireless #internet providers who provide the connection anonymously. In this case even gsm, #lte, or #3g could be used.
