I bought another computer today. Big News. But it is really, really, nice. And cheap. Pocket C.H.I.P.
It's based on a nine dollar device that is quite astonishing in terms of what you get for the money, which is a 1G processor, 512K of RAM, 4G of built in storage. Plus WiFi, Bluetooth and the ability to add video displays and any USB device that your particular flavour of Linux will support.
It looks like a worthy Raspberry Pi competitor. I've gone for the Pocket variant, which comes with a case, a nice looking (resistive) touch display and cute looking pink labelled buttons which might match your nail varnish. Or not.
