The Raspberry Pi $35 Linux computer sold out within hours of going on sale in February - with demand for the device reportedly hitting 700 orders per minute.
The upshot is a lot of people who wanted the credit card-sized Raspberry Pi have been left empty-handed - with anyone ordering the device today unlike to receive one until about July.
Fortunately, the Raspbery Pi is not the only pocket-sized device in town. There are a variety of alternatives worth considering if you want to get your geek on with a relatively low-cost, portable computer.
Like the Pi but with a bit more grunt under the hood and a higher price tag, the $180 PandaBoard ES is suited to both PC user and developer.
The diminutive board is based on an open-source hardware design, and can run several flavours of Linux, such as Ubuntu and the Android OS. Support for a range of add-on boards allows the device to drive motors, run sensors and power LEDs, or anything else an electronics or robotics enthusiast might want to do.
Among other things, PandaBoards have been used as media centres streaming 1080p, as control units for robots, as a wearable computer, to run a gesture-control interface, and as a general-purpose Android dev tool.
