HMMM Just thinking... what if Linux distros used HTML5/Javascript for a GUI Desktop Shell (Like Windows 8)? What if it became a true cross-platform development environment?
That's fair enough considering Internet Explorer, but there are some counterpoints to consider:
(1) If you watch the MS promotional video, attracting a wide range of developers is a stated goal of using HTML5; it would be counterproductive to that goal to add lots of proprietary code.
(2) It would be easier to stick with the status quo than to recreate HTML5.
Their goal is to protect Windows from the competition. Providing proprietary hooks that cannot be easily duplicated elsewhere is their most likely strategy.
'Not sure why I mentioned Linux and not OSX, possibly because I was jumping ahead to wonder if this could solve the Gnome/KDE/Unity debate (but who am I kidding?)
I asked myself the same, lol, OSX is lagging behind when it comes to accepting HTML/CSS/JS as a first class app environment... Except for Dashboard Widgets, of course.
