i know a lot of people who download music, and they're always surprised that i have for years had a recurring rhapsody membership. all the music in my mp3 players is from rhapsody, all nice and licensed.
i work on the internet and years ago winzip had a trial that allowed eternal use of winzip - the only thing to stop people was their terms. know how well that worked? when a webmaster posted a thread on a business board asking how long everyone had had their unpaid version of winzip working, almost everyone was at 4+ years, a few at over 7. and these are webmasters who are always on the lookout for people who steal their intellectual property.
i, btw, have a registered copy of winzip - but then, apparently i'm a weirdo
