From the website http://www.raspberrypi.org/ this little thing has a lot of feature for the mordern day but with only 250 meg of memory. Ideal for the basis of a new QL was my first thought, in fact you could quiet easily fit a few of these inside the QL case, replace the QL keyboard with a proper one add a decent size battery and you have a portable computer.
Seriously this device is designed to inspire young people back to the fun of programming, and I say hurrah!, what an achievement and something QL Users should look seriously at, for re-configuring for SuperBasic, or even supporting directly. A caveat of course as the device isn't out yet (later this year apparently), but it it does and at the price stated, it would be so cool. It will come configured and runs UBUNTU so to me it will run a QL system. WTS
