Rather for comfort reasons. But, yes, surely they would be seen as a hassle, when there is a system which works, and requires less work. That's also what I said earlier: Why would there be a reason for a physical dongle, if it all can be done virtually on your computer?
What I rather didn't understand is how people can argue that a software should have no protection at all, and they feel like thieves when there is such a protection scheme. That's something I don't understand. I never felt like a thief when I have to ring people's door bell, or wait until they unlock their cars. Actually, it's pretty short sighted to argue for no copy protection at all, because, it simply will lead to developers having to make up for the loss of piracy, meaning that the software will have to be more expensive.
