Netscape was a slow-*** p.o.s. IE was better than Netscape. MS got complacent with IE and then Firefox came and kicked their asses all over the web. If Silverlight on mobile devices works out, then to heck with Adobe.

You're right, there does seem to be some third party implementations of Flash. My mistake.

The comparision between flash and silverlight is actually probably not a good one. I think AIR is probably the closer analogue.
