Very consumer oriented viewpoint, but that's the one that drives sales, or at least used to, so no fault in it. These days I think the corporate market is a much bigger slice of the pie over at MS than individual consumers.
I didn't buy XP or Win7 for the enhanced security or any of that, I bought them to play games. My job doesn't require anything that Win2k can't do; hell, If the latest JVM/JDK or recent browsers will run on NT4, that's all I need for work. Edit text files. SSH to servers. Manage vCenter. That's all I need to do with a computer beyond the realm of entertainment.
Others have similar requirements, be it using Eagle or ArcGIS or whatever other specialist software package they need in order to do their jobs.
Win8 is not even a slight improvement over Win7 or XP at such tasks. Not only is it "dead" on the consumer side due to a dying desktop PC market, it's dead on the corporate side because all it brings to the table for existing users of XP, Vista, or Win7 is aggravation. MS needs to refocus Windows on corporate and business users and drop all the 'fluff' or I have a feeling they'll lose even those markets entirely.
Which sucks, because despite their faults, the NT based OSes have always made stellar workstations.
