The low bandwidth quality SL content easily beat the high-bandwidth quality of Flash streams on sites like Hulu and Amazon VOD.
It simply doesn't matter if anyone has Silverlight installed or not. If you build a killer app with it, users will install it if you tell them to. How do you think Flash got so big?
Not if they can't. What's the current best selling hardware category in computing? What OS do they use? Does Microsoft provide a stable, working Silverlight plugin?
Maybe microsoft installed it itself in my xp but i will never install it by myself. They bundle it with messenger, live id, explorer toolbars or who knows what.
If this is true, Microsoft is doing better than I expected.
(And I'm a .NET developer, not one of those politically opposed to Silverlight because it isn't free enough for their particular preference of free)
