I use a Holga as well (and greatly enjoy it, I even won an award with one) but part of the enjoyment is the unpredictability of it. You just never know what you are going to get and if it is usable. You have to admit it is very much a "pet rock" type of item, something that very in vogue at the moment but will likely not have long staying power.

I think you are taking his reference to fools a little more personally than he intended; he is saying that the person who thinks the Holga/Lomo is the high-point or a complete representation of film photography is a fool, not the person using either.
