The front of the new Samsung SGH-i450 slides down to reveal both a touchwheel-controlled music interface and an honest-to-god speaker. I think the way the on-screen UI complements the arc of the physical speaker is really nice.
It's only for Europe (along with some other sharp models), so it's no immediate threat, but I can't decide what would be worse: listening to guys on the subway blasting their music out of tinny, clipping cell phones—this already happens—or listening to their music out of higher quality speakers at a higher volume. They'd probably just turn them up until even the better speakers clipped.
