Although a bluetooth keyboard using Pyra parts has always sounded cool, at this point, small bluetooth keyboards with game controls are everywhere.
However, there IS still a niche unfilled...
Pyraminal?

"If we want to get REAL fancy on this idea, use the whole Pyra shell, display, keymat with a dumb CPU board that flips the Pyra's HDMI output into an HDMI input. Then internally hub the USB connection into power, trackpad touchscreen, usb keyboard, joystick mouse (nubs). Effectively this version would be a Pyra terminal... Pyraminal? Hypothetically, this could use all existing Pyra hardware and just need a different CPU board with very little CPU, nearly no RAM and not much eMMC that stands all of the connectors on their head to be clients instead of hosts. It would be a pocket KVM - just connect it to USB and video output on the host computer. Holy crap - a person could even hook one up to a Pyra and play multiplayer games."
