We've been waiting for Microsoft's Silverlight since, oh, April of 2007. Since then, we've seen demos, had our expectations raised, brought back to earth, and raised again. Well now it seems that the mobile version isn't too much further off. Turns out it was slipped in sideways inside a Windows Live photo gallery 'Community Technology Preview' that leaked out.
Silverlight seems to have lost some of its initial momentum of late and nobody is claiming that it's going to take down Flash. However, as we said back in June (seriously, a long time we've been following this stuff) when we saw a WeatherBug demo, Silverlight has the potential to bring some whiz-bang UI to WM. Would be nice to see it.
