I ventured onto Windows Phone 7 website... not as if I was planning to change my N900 for that, just to see what they are up to. Anyway, I found a video link from engadget (same subject) using silverlight. Then on the Silverlight website I saw that they mentioned it for 'mobile devices', I don't know if it means laptops or phones(other then MS) as well because the only 3 links were for Win/Mac and Moonlight for Linux... No Android or Symbian link to my knowledge. It would be nice if Moonlight was ported to Maemo and Meego though, since I got a feeling that we'll encounter more of SL in the future.
