Is there anything out there for custom ROMs for one of these? The cnet review says it doesnt support android market, gmail, or google maps which would suck?
This is incorrect. If you look about, (Even on AppsLib market) is a Android Market installer. I use the GAppsinstaller_V5. There are others. Just do your research
There is an ArchAngel Root. But this is not required to install Googles Android Market.
