Apart from old laptops, that is, I have just two Linux boxes. And they haven't had an upgrade in months. One is my MythTV box which is running an now quite elderly version of Mythbuntu. The other is my EC2 instance in AWS running my email.

I gave up running a Linux desktop at home when I discovered Windows 8 was actually alright. Especially with a touchscreen.

I have a contractor colleague who is probably older than me who still farts around with VMs and database clusters at home in his spare time.
