The Android handheld I reported on earlier has now also become available for sale on the company's updated website. There's an order now button where you can place an order directly from the manufacturer or request additional information. The manufacturer is located in Hong Kong so it could be that you will have to pay additional import taxes according to your locale. Getting one from a retailer locally would be your best option but if that isn't an option going the direct route may be a good alternative. The unit comes in a sturdy box and is well protected by a specialized air filled sleeve. A charger compatible with your local AC power grid is also provided.
There's also a very informative video explaining how the VKM - virtual key mapping software - works. This has been substantially updated since my video as it is now also possible to map swiping gestures onto the buttons (right thumb stick).
Performance wise this unit is capable of full speed emulation of many game systems, including the PPSSPP and original Playstation. Also many games, run great and the battery life on the unit is quite good. The developers of the RetroArch emulator have gotten a unit too so one can expect an even better native support for all buttons in future releases of that emulator. Hook the unit up to the TV over HDMI and you'll have a great console experience. Blue tooth, wifi, microsd slot - all is there. The amount of flash memory 8Gb is similar to the OUYA and in real life comparison - side loading the same apps onto the OUYA - this unit trumps the OUYA on real life Android apps despite the fact that in theory the OUYA has more beefy hardware. There is no lag on the GameMID's buttons and it seems to be my gaming tablet of choice at a great price. A lot of the Android gaming videos on this site have been recorded using this device. Check them out if you want.
