This is one of the clearest and fair comments you'll see regarding the "controversy" over Windows 8 UI. He likes it!!
I, don't particularly care for it for some of the reasons mentioned in the article - it was designed for a tablet/touch operation and adapted to the desktop. I can make the change and adjustment but "prefer" not. Oh yes, I built and maintain 10 desktops and one laptop (purchased) for friends and family using XP and 7. For my users, the functionality is very similar. My users are also not computer literate in the least. They can do what they want however, such as browse, email and run some other applications. Any minor, and it is minor, speed or performance increases in Win 8 will have no benefit to them whatsoever. They, like myself, enjoy their main screen (desktop) with a wall paper of their choosing. I have a 26" Sharp Aquos monitor - nice HD tv also. I don't need a full screen app when I can currently open several apps and see all of their display or most of it.
So, I prefer XP or Win 7. If someone really likes 8 that's fine. Wait until these IT departments have to train people to operate it when it will do nothing to improve most employees productivity.
The rancor over this is incredible.
I work in an IT department and we don't have to train any users on how to use any OS. We show them how to get to the applications they need to run and we don't want them playing around with the OS. We actually try to give them restricted rights so they can't damage anything. Now our IT staff will need to be trained on it just like we have to learn Server 2008 after using 2005 for so long.
