They can't fix the annoyances of RT. The main problem is that it looks exactly the same as Win8 and people *will* be misled in store. Then go back to the store and ask the rep: "There is a problem with my new laptop (tablet)" I downloaded (Firefox|vlc|chrome|whatever) and it doesn't get installed"

Tell me what would you do if you were that rep, the next time a possibly clueless customer is courting the Yoga 11.
"Dear sir, this is not a real PC it cannot run your favorite software, you know that, yes?"
Still wondering why it doesn't sell?

This cannot be fixed unfortunately. Linux on ARM makes sense as you still have all the apps in repos, readily recompiled for you. It is impossible to recompile the world of windows, and an emulator is out of the question, not enough grunt.

They lost their chance to make that work. If they released RT with a home screen different enough and without a desktop it could have worked.
