In all seriousness though .20 cents an hour is quite low. While free apps certainly don't pay out much getting a paid app for essentially nothing is a sweet deal (at least in my mind perhaps I'm wrong).
Developers putting their apps onto users devices and users (who might not normally download apps) trying out new and exciting technologies while making a little spare change doesn't seem to hurt anyone, in fact I'm banking on the fact that people will find value in the service.
