Commercial Stockholm Syndrome

I was in a discussion today regarding PC's versus Macs.  The gentlemen I was discussing this with used both, but was obviously biased towards Macs.  when I asked him "if Macs are so much better why do people stick with PC's".  His answer "Stockholm Syndrome".

I was quite amused.  Do you have any prospects who seem to be abused by your competition, but find it hard to switch?
