OK, I get it.
MS has created an all-in-one OS that will run on PC's, tablets, and smart-phones.
What works on a tablet or a smart-phone screen doesn't necessarily work on a 27" monitor.
Still time to make a few more tweaks before final release, Microsoft.
Why not just code METRO as a plug-in for the desktop environment and make everybody happy?
Choice is good.
Just saying ....
