How to do demo software in a way that doesn't piss me off

Good: 15 days of full functionality, so I become dependent and enamored, and then throw money at you, happily. (http://www.assistiveware.com/keystrokes.php)

Bad: reset every 20 minutes, so after an hour I hate you, and am off seeking alternatives. (http://www.orin.com/access/softype/)

Send this post to the developers. Your 2 minute email may get them to see the error of their ways and could help others in your situation in the future.

If they don't respond either to you, or in a subsequent version of their product, I assume Softype will die a natural death.
