Re: I'm confused*
Drivers for esoteric hardware? That's the classic reason for science labs to keep antique kit running.
Or maybe they value stability over all else and don't want to risk a migration. That's the reason that a lot of hospitals still use WinXP. I was seeing IE6 in my logs for a clinical trial progress tracking website last year.
Incidentally, I spotted the Sun Microsystems badge in one of those photos before I got to the line about kit from companies which don't exist any more. Been a while since I saw that logo.
