You be interested in the rhombus-tech project. I describe it as future
proof computering and now you can put a order in for first product which
I have just ordered myself. It's £60 including post and tax. That's darn
good for a first product, free/open hardware, libre/(free as in freedom)
software supporting hardware but also not bad for the spec. Shipping in
Jan 2014.

Profits go into new products not share holders.

This is being sold by the project doing the first tablet.

The tablet has been sent off (in Nov) too the factory for final approve
then it ramps into production :).
