Zero investment of my time or resources - I already know how to eat pi - nothing to learn or experiment. If it is the same pie I had before and did not like I don't even bother to try it. Of course if it is different than pie I had before I might try it but apparently I should not even ask.
Personally, it takes me less time to decide whether some new software is crap and not worth my time than it does to eat a pie.
