What happens if you sign up for the payment plan and stop paying after four months ?
Paul, as I said in an earlier post, think of it as "rent to own". If you pay monthly, you are renting the software. Stop paying, you stop having access. However if you rent it long enough, you own it, and get to keep it forever. Of course if you buy it up front you also own it forever.
When I was a kid, there was a tool store like that. They sold all kinds of home tools, and also rented out higher end stuff like sand blaster, compressors, paint guns, etc. You could buy any of that outright, but you could also rent it. Twist was, the rental money you paid counted towards ownership (at a higher cost than buying up front). If you rented it enough, it was yours. This appealed to multiple groups of people:
--If you were a construction firm or something, you just bought it straight out, as you normally would.
--If you were a home owner, you could rent tools that you didn't need often, and didn't wish to afford. One summer my dad rented some big sanders, a compressor, and pain gun to repaint the house one summer (not the most fun summer for me).
--However if you were a small contractor or the like, you could rent something with out committing to buy, but if you ended up using it all the time, you got to keep it, rather than having all that money go nowhere.
Same deal here. You want Sonar? Buy it. You get to have it for ever and ever, just as you did before. You just have a small project and want to rent it for a bit? No problem, rent it monthly for as long as you need. However, if you find out you use it a lot and keep renting it, after a year you get to keep it like you'd bought it up front.
