Well they would say that, wouldn't they.
Seriously, I like Silverlight a lot and HTML5 is a long way over the horizon, But I thought MS have pretty much stated that they no longer intend to push Silverlight onto every platform and will go with HTML5 in the longer term. Also sort of interesting that Symbian still accounts for about 40% of phone OS's and Nokia are cuddling up to MS....
Anyway none of this impacts on my market for the time being - no axe to grind....
