I guess that one could download a few demos and spend time on Youtube, but that doesn't leave much time for
anything else:work, for example or time to play the demos and try out whatever else one might have downloaded.
I don't think that an uncapped account is a invitation to go wild and grab as much as one can, only a means to
use the resources the internet has to offer without having to worry about watching every last kilobyte.
