Are they you ask? I think so and, quite frankly, it really annoys me.
SilverLight is a platform that offers a lot of potential to the tablet community as it opens the door to real ink on the web. It is also a direct competitor of Adobe flash. Flash is well established and SilverLight is the new kid on the block.
To gain real acceptance in the market Microsoft need to convince developers to choose SilverLight over Flash. The more developers that are using it the more widely the browser plugin will be deployed.
So why are Microsoft still using flash on their sites? I've seen this on a couple of MS sites lately - but tonight it was on Zune.net. I don't get it.
