I would do neither 1 or 2.

Media types is a broken approach, for two reasons. Exclusivity is one,
and the fact that people will think of of new devices all the time
makes it a problem.

We should keep media types as they are, but focus future development
on media features.

When you want to make a TV style sheet, is it because the screen is
big (and far), or because it has a limited input mechanism? Could be
either, could be both, and depending on that, maybe your style sheet
would also apply to a projector, a poster, a gaming console...

Here are some examples of things we should be able to detect through
media features: continous vs paged, touchscreen or not, updatable
vs static (paper, e-ink...). There are certainly many more, but
the list isn't quite as subject to explosive growth as a list
of media or device types would be.

I believe this approach would work and scale much better than media
types.
