This is an interesting take on the whole gameboy-zero modding thing. Instead of hacking up an old gameboy, this is a complete system (roughly the size and shape of an original gameboy) that can be assembled without tools. The case, display, motherboard, battery, controller, and speakers are all self-contained components, and can theoretically be upgraded in the future. They even indicate the components can be used separately or in different combinations. Specs are nothing mind-blowing, but should be sufficient for the sort of games you'd want to play on this type of system: Allwinner R16 quad core cortex A7 (unknown clockspeed) CPU Mali 400 GPU 512MB DDR2 RAM 2.7" 320x240 LCD MicroSD storage Wifi Exposed serial & GPIO points (on a ribbon connector, I think) 1050mAH battery (3hrs est. runtime) Stereo speakers & headphone jack The "openness" of the system is limited to the OS (linux) and physical design. As with virtually all ARM-based devices these days, don't expect anything besides binary blobs for drivers. I'm very skeptical of the control-feel from a tool-less, modular system like this. I expect a lot of creakiness, and either binding or slop in the buttons and Dpad. Still, not bad for $90 if you snag one of the super-early-bird units. A little less impressive at the full price of $140, I think. Kickstarter link.
