New submitter mpicpp points out that Intel has unveiled a PC called Edison, which fits into a casing the size of an SD card
"Edison is based on Intel’s Quark chip, which it launched last year as its attempt to muscle in on that other flavour-of-the-month market: the so-called Internet of Things. It also reflects the company’s new-found keenness on the 'maker' community. Quark, a 22nm low-power x86 processor with two cores, sits inside Intel’s Arduino-compatible Raspberry Pi-alike Galileo board computer. Edison takes the same chip, connects it to a wee bit of LPDDR2 memory and Flash storage, and plugs in Bluetooth 4.0 Smart — aka LE — and Wi-Fi for broader connectivity."
