I think the software world is heading in the same direction as music - not making the millions anymore, so having to resort to weird and unusual sales solutions to establish a predictable income... I don't mind renting, but then I want 110% reliability and compatibility. Just like a rental car - you give me a bad one, you'll sure as hell hear from me.
Next we'll be renting air and fresh water too.. Oh, wait, Nestle is already trying to justify that logic.
