Yup. IT in big corps really needs to change. I have - beside the Windows Update - the "Your IT department (...)" update, coming daily. Most of the time, it's a new wallpaper, which I have to disable via register tweaks.

The example you gave - the pain of sysadmins using the Windows desktop - is perfect. But let me add a different one: the big corp where I work decided that iOS apps were needed. I can't even begin the describe how long and cumbersome the process of acquiring a Mac was! It was so ridiculous that we used personal devices for a time, and then a Hackintosh.
