This is one heck of a off and biased comment; but I'll address something a bit less emotional just for the heck of staying on topic to the discussion. Silverlight, like Flash, like QuickTime, like Shockwave, like Java, etc. is a runtime environment. MS built it as a competitor to AIR and Java. The latter is one that suffers from a ton of brokenness and performance issues on EVERY platform. To date, SL has proven to be faster and less CPU intensive than Flash. And any RIA apps that have been developed with it were done easier than any that have yet to come via AIR. In terms of Nokia's part in this, its a smart move to get Silverlight into the mix. One, because more and more apps will be connected and therefore the browser and any runtime environments will be the places to battle for developer attention. And two, because by announcing this, they can keep the pressure on Adobe and others to further pay attention to their hoard of mobile devices, and make sure that current implementations of said software are not the last versions. Expect to see SL driven apps as part of any Qt initative since that port is already something in progress. As for not wanting MS on your IT none; that is definitely your choice; but its users that also have a hand in making this call; if more users like the SL apps on the tablet, guess which runtime developers will spend the most time in towards making quality apps?
