Frustration is understandable, especially when a person has spent a lot of money on something.
What doesnt help however is long winded, excessive, negative tirades (both against a persons preference, or an alternative) .
Its this sort of behaviour that has turned me off of spending money, and really delving into the ppcoptions. As they say its a few that spoil things for everyone. Not that AROS doesnt have the same sorts of people, but free is a much more appealing price and easier to walk away from should community members piss you off to a point you want no more of it.
Its a bit of a shame really. I have friends, and know people that I like that use pretty much every amiga related option out there, but those few, self absorbed, self righteous people who think its all about them spoil other peoples hard work.
