I learned a long time ago that people can justify purchasing almost anything, whether they have the actual money for it or not. I'm guilty of it myself ( as I have bought pets and such for WoW ) but its something I generally don't do anymore as I beat my own self up too much afterwards. I'm sure some people bought it and had a blast with it, but I'm betting there is a group just as large that bought it and wish they hadn't wasted that money now.

Anyways I will never tell someone they shouldn't spend their own money how they wish, that doesn't mean however, that I won't think they are stupid or supporting a really bad idea.
