"Why shouldn't they use XP to drive the projector if it's a stand-alone appliance?"
While there are a variety of reasons that could be cited regarding best practice and so on, the most obvious reason they shouldn't is that it might crash in the middle of a performance. It's all very well to claim that an old OS can still do a perfectly good job in certain circumstances, but this article only exists because said OS demonstrably did not do a good job.
