Yeah, the occasional bold word, inline link, heading or even the occasional image can make a message much more readable. If you don't like bold words your client can ignore that tag.
I think this is partly an over-reaction to some senders that go way overboard with bright colours a hundred images and complex layout that doesn't render right on your screen size. But just because a capability can be used poorly doesn't mean that it can't be used well.
I can also understand that some people choose to prefer the text version of messages because it is so common to "abuse" HTML. And for those people I even include a text fallback in case their client doesn't have the ability to do that.
