Nvidia Project Shield

This portable gaming device claims to redefine gaming on the go. The Android gadget, with top-of-the-range audio and visual quality, lets you play high-quality games away from your home. You can also connect the device to your PC using wifi, so you can play your favourite games without having to get off the couch. It's still in development, but should be shipping to the USA and Canada in the second half on 2013. Nvidia say they want to ship to other countries, including the UK, as soon as they can after launch.
