I will not miss XP. I have not used it in years.
My desktop is Server 2008 and my Admin PC is running Windows 7. It works very well for me but I will be reversing the rolls in about a month.
My Desktop will be Windows 8.1 and the Admin PC will be running Server 2012.
Running the latest OS's on my everyday work systems helps keep me in front of the learning curve.
In other news, I am really upset they killed Winamp!!! If only iTunes was as easy to use!!!
