I can live with subscriptions, though part of me rebels at it. But I really dislike software that makes me pay ahead of time to even try it. This isn't exactly common, but it is seen at least on the Apple app store. In a world where subscription models are so common, what makes it hard to give me a 7 or 30 day trial before I have to put out money? I've had to ask Apple for money back three or four times, and that is both a drain on my time and attention as well as (possibly) some poor schmuck at Apple.
