This is very simple. The enterprise won't adopt it right away. There are many reasons. The .5 are mostly beta testers in the IT departments in their labs testing the software for compatibility issue and OS training. I am assuming that most will skip 8 altogether and go to 9, but that will depend on what is required on the back end/servers/software upgrades/etc. We are just getting rid of xp now and adopting 7. In 2018 we will be testing MS newest OS and adopting that. Mac and Linux aren't an option.

Why would Paul want to adopt any part of YOUR lifestyle, wally?
