i think i can be pretty cool, silverlight had focus areas that arent really needed for the deskop:smalldownload size, cross platform considerations, but for winRT you want to max out the utilization of the hardware
i think silverlight and willl phase out and be replaced with winRT, but its all xaml so its not a huge jump.wpf willprobably stillbearound for though heavy applications like VS, but we'll see... perhaps even better would be if winRT encompases wpf functionality as well
