I had a seriously nice mac mini taken off me once, got given a "new Mac Pro". Was huge downgrade, was not happy.
We got docking stations for the laptops but I just couldn't get used to it, and my desktop was just sitting there still functioning happy as could be.
So I still use my desktop for actual work and my laptop is basically a very over-powered video conferencing machine.
