@cypnk Exactly! I'm pondering this idea for couple years now.
I'd love to have the same/similar subscription for software as well, honestly. I don't like paying upfront for some web or mobile apps when I have no idea how long I'll be using them or the underlying platform. It's hard to judge it's true value for the price. It would also solve the platform lock-in. Payed for iOS app already? Fine, you can also use the #web / #Android / #Linux app, it's app :) to you.
