My views on (current) software are very much the same as they are on music mp3's: I try it first and if I like it, I buy it. Simple as that. I can afford software and music. But what I can't afford is to toss my money out for bad software/games or CD's that only have one or two good songs. In the case of some bands, I will buy their CD if I only have four or five mp3's and they have the same consistency. The only way I can keep getting the music and software I like is to support it.
Oh yeah...there is always the price point, too. All too often, these products ream the buyer, so I think they get what they deserve from pirates. Fair is fair and everybody knows when the price point is gouging the consumer.
