While I appreciate the elegance of good hardware design, I’m a software guy at heart, a programmer. Programming is a way of thinking that combines tinkering with a problem and exploring its constraints to arrive at a solution that meets those constraints as best you can.
Nevertheless, I’ve just ordered the device from Farnell, showing 54 days for delivery.
So meanwhile, software. Programs. Algorithms even. I installed installed the Rapsberry PI emulator from here and have a working image. It’s a nice, minimal Linux but it it is clear that there would be a lot to do before it could be considered a suitable working environment for kids like the Xadros Linux on the Asus eeePc I bought a few years ago.
