What I also found interesting at the lockergnome was Chris' article about the survey of 50,000 W8 users here: http://tinyurl.com/cxx99at
Of the people surveyed, 53% state that they prefer Windows 7. Not happy making for MS.
My hope is that Start8 will bring a large group of folks who might be unhappy about the W8 Tiles to notice SD and make W8 usable. I don't want to see MS fail. I'd much rather see MS and SD succeed.
