If the stick has enough power to play the majority of MAME games, this might be a nice addition to the home entertainment rig. I bought an Ouya a couple of years ago for this purpose, but I just didn't like it. Running a TinyXP installation on this stick with MAME32/MESS32 with a Bluetooth keyboard w/ touchpad from my comfy chair would be pretty sweet.

The CPU on this one is the same as on the Intel Compute Stick, a Z3735F.
