we had all solaris with a few xp labs up till about 2005. I kinda miss the ultra 10s and sunblades. I usually set up at one of the ultra10s with 2 19in CRTs. lots of space, and the sun labs were usually pretty vacant save for the stray cs/engineering crossover student. they kept red hat machines in the place of those ultra 10 when we got new optiplex's and lcd monitors.
