Ty you Sir. This series helped me a lot already although i didn't finished it still. Huge respect!

When I'm here already I will be free to go off-topic and ask a serious programming guru  like you are about few concerns i have. First of all can Desktop Windows 8 application interfaces be made with html/css/js? Also in future how you see js versus c#? Do i need to focus on mastering  js or c#? I know in base js is a lot simpler, but can be "extended" with libraries and be as near as powerful. So who will prevail for front-end development? Thought my heart is on the side of so called Web Standards Model.
