So called 'donation' or 'tip jar' type is pretty old too.
Shareware was the original free trial. Then we just started calling it a free trial!
Advertising is old as hat, been funding not just software, but many things, for a long time.
I'm having a hard time thinking of the different ways you can actually sell your software to someone, and in an app store dominated economy, where its idea of how software is paid for really has a cascading (and I would argue detrimental) affect on how all software is sold/distributed/licensed/modeled.
Am I missing something? I'm all for high ideas. I just don't see anything short of revolting against platforms that even come close to difference.
I'm all about options. In fact, i'd love to hear some.
