I work on a laptop running Ubuntu #Linux. I can access almost everything I need from the work network, mostly using the Chrome browser. However, for a few things, mostly Adobe's proprietary extensions to PDF forms, I need Windows. I have a virtual machine on my Linux computer for this purpose.
Starting it up takes *minutes*, and opening Acrobat to fill in a single form regularly takes 15 minutes or more start to finish.
I've also got a desktop running windows in the lab down the hall. Once or twice a year I'll think, "this is dumb, I can just walk a few steps and use my Windows computer for this". So I do. And it takes *just as long* to go through all the boot/log-in/setup steps as my virtual machine.
It's a wonder we get anything done with #gc IT systems.
