Windows 7 replaced Vista and XP. It works very well, whereas Vista was iffy at best, and XP was getting a bit stale (although it’s still fairly functional).
I don’t see a compelling reason for corporate desktops to change from Windows 7.
Inroads will be made in the tablet area, and possibly with Surface and the Nokia products. Until those really catch on, I don’t see why anyone would want to change over their desktops for consistency with the new Metro interface. And, if you are going to keep the old interface, why bother at all?
I bought a Toshiba laptop this summer for work, then one of my business partners bought a new Dell for our receptionist with W8.
Our receptionist after 30 minutes went nuts. like she wanted to cry.
The interface really gives you a headache. Try even looking under “MY COMPUTER’ for our external hard drives and another 1000 icons popped up and it took us 10 minutes to find the damn hard drive.
The only reason you might is for manageability features. The change in user interface is disruptive.
Server 2012 has some nice features, but it's got it's own change in UI going on in the opposite direction. The default installation is Server Core, and the UI is a command prompt.
I have a Windows 7. Soon to go bad. I am fed up with buying a new computer every 2 or 3 years because of crashes. I do bookkeeping. I am going to get a Mac.
Neither do I - for I've already gone back to Windows 7.
