We launched in December 2012 our offline desktop software product for business and freelancers (niche market with a TAM of about 100,000 users) only as a subscription, no perpetual licenses available. Previously this project was freeware (closed source) so our 2.x version remained freeware and our 3.0 was only available as a subscription sold in chunks of 1 year-subscriptions as opposed to monthly). In retrospect, we are very happy to have chosen the subscription model because it resembles a lot the freeware model: for maintenance you just focus on the latest version/build issues because 100% of your customer base is entitled to have it, you don't compete with yourself across paid versions and don't need marketing effort to explain customers why they should upgrade every year. Your sales effort is also lower because your price point is lower.
