Gaming on Batteries Triverse writes, "If a five inch screen is just too small (as in the GPD G5A) then check out this other tablet from GPD, the G7 which has similar specs but adds on a 7 inch screen and Bluetooth support. This is something that is missing from most tablets today, at least the ones that are gaming tablets and feature hardware controls. Bluetooth may not seem like a big deal but there are a lot of things that can be used with controllers while hooking the GPD up to an HDTV (no wires and no hassle)."
