Has anyone seen any reviews of the M6 Pro? It's basically a GPS-version of the standard M6. It can be found on the official Pipo site, ebayy, ali[expr]ess and other retailers but I can't seem to find reviews or forum threads about it. Is the M6 less popular with custom ROM developers than the M9 / M9 pro? I much prefer the 4:3 aspect ratio of the M6 but don't want to be stuck with a tablet that has little support.
