As it stands today, if someone pays X dollars for a month, they can download (the current revision) and it reverts to demo mode. I cannot think of a single instance of potential customers being charged to demo software.
You could try Cubase or ProTools - they both demand a dongle to demo. That's $20-$30 right there, if you don't already have them. You can run Cubase Elements trial though - without any dongle. My thinking is - if you're not ready to spend $10 to run for a month, you are not that interested anyway.
And after that it's reverting to demo mode - don't know for how long, if restricted at all - but you can demo all you want even after that, in a similar fashion as all demos do(except Reaper then, that never expires).
I think the demo debate has lost all proportions. Good that Cakewalk put all efforts to provide updates on a regular basis. Not spend rediculous amount of effort on making all shipped plugins revert and similar things. No matter what they do - they will not please everybody...
