Cross-Platform CLR

Sam Gentile enthuses about the availability of the CLR on the Mac. Another thing is that Mac users, like PDA users, appear to be more willing to support small/Micro ISVs. Whether that would hold true for a Silverlight (i.e., non-native) UI, I don't know. But maybe I'll buy my first Mac since the F/X on which I learned Smalltalk circa 1990 (?).
