Android Market Map - Circa November 2010
Purple = Paid and Free App Support
Blue = Paid App Support (I'm looking at you Ireland)
Red = Free App Support
Made (and also available interactively) at GeoCommons: http://geocommons.com/maps/35036, using Google's current listing. I'll update this as the market support is updated.
GeoCommons, an online GIS, was a breeze to use once I figured out the basic workflow for creating datasets. Worth checking out.
