Started out with two Sun2s on my desk, running SunOS 4.0.1, and Xview! Those were the days... took almost 10 minutes for the windowing system to completely come up. Whee!
After many years in UNIX (mostly Solaris, some SCO, HP-UX, etc.), started dabbling in Linux in the late '90s, a bit more in the early '00s, and now I'm up to my elbows in CentOS 4.4 with KDE 3.5.6-4... and liking it!
