In 2010ish I worked briefly in a school in the UK (ages 11-19) which had 3 or 4 racks of servers running Citrix XenApp, serving Office etc. and general educational and administrative applications to ancient laptops and desktops which had been (very inexpertly) reconfigured as thin clients. It ran like crap (probably didn't help that re-provisioning a server was defined as hot-swapping disks around and running NewSID or whatever it was called) and of course in large parts of the school the WiFi just wasn't quite good enough. I got a lot of calls from PE teachers trying to take the register from the far corner of the playing field. It was an extreme case of CV-driven development, I was brought in to backfill when the IT manager who had introduced all this walked out one day. He stood up at about lunchtime, grabbed his coat and said "I'm going now". The team thought he meant for lunch... By the time I was leaving under a year later, they had brought in another IT manager who (rightly!) said "what's all this nonsense" and rolled out proper clients imaged with MDT.
