I plan on upgrading after a few get bloodied going through the wall first...
I've deployed half dozen in our organization for business use, NO ONE likes the Metro interface.
We've used software on each to mimic Win7 experience.
I'm an avid Firefox fan, but I'm looking forward to Edge, specifically how it works on the tablets with highlight ability, etc.
I'm interested in Continum as well, I often take mine off the dock and go into meetings and demos.
I realize the start menu will be a hybrid of Windows systems of old and Metro, but it's got a desktop feel to it.
I realize, like anything, it will continued to get polished as time goes on...but the features listed have me interested for sure.
