I read this and thought it was very poorly written and also quite unfair in some areas. The windows solution could have been done far, far cheaper than what was suggested there, in fact the student system's price was completely ludicrous. I also think there was a lot more bias towards Unix, for example, the choice of thin client like workstations wasn't even attempted using NT Terminal server, and therefore it wasn't really a srict comparison.
