Adobe stopped to sell their software, it goes all Subscription base business model. Even Microsoft sounds more keen to sell Office 365 Subscription than their Office 2013. I believe that is a future trend. The users can apply a subscription fee which is relative cheaper than a one-off fee to own the software. Moreover, the users always can get the latest software with the subscription. That sounds cool. But the users need to renew their subscription annually or monthly. Well, even we buy the software, we need to buy a upgrad version every few years.
