Andrew - at the end of a care lease you pay the REMAINING VALUE - i.e depreciated value. 700 is the FULL NEW price for Photoshop. Upgrades cost 200. People may find a 100~200 "keep it" fee reasonable after paying a year or two of rent.
I know <g>. But 700 WAS the full price and it bought you a perceptual licenses too, so thinking different (like Adobe <G>):
Here's the deal. Adobe can't have you subscribe for 3 weeks, then decide to end the lease. They would probably have to have a minimum subscription (or like your phone, you pay a fee to get out). So you pay $20 a month or whatever for just Photoshop. 1 year, $240. Then after that year, let's just say you can 'buy out your lease" for $500. But what about the fellow who's leased, I mean subscribed for 2 years? Can't change them $500. Or can you?
IT can't be too complicated but should be a lot simpler than figuring out a end of car lease fee. Since Adobe knows how long you've subscribed, maybe they have a 1-2-3 year fee for the buyout that differs. Remember however, Adobe got it's $700 initially and wants to stop you from doing that once and never again, so I suspect if there is an out, it's going to cost you big time. But at least, there's an out!
