Douglas Adams had the joke about the phase of an immature civilization's development in which it believes that digital watches are a clever idea. Digital watches are still fairly popular (mostly at the cheap end of the market), and I never had quite the antipathy to them that Adams did; but in that connection, it occurs to me that I've personally witnessed the end of the era in which humanity's nerd vanguard collectively believed that the logical place for any arbitrarily advanced item of personal tech was on one's wrist. For a time in the Eighties I actually wore what you might call a primitive wrist PDA, a Seiko watch that could store a few text messages (you entered them using an incredibly painful browse-the-alphabet-menu interface). And those Casio calculator watches were all over. I never saw one of these, though.
You actually can buy a wrist TV if you go looking for one, but only a high-octane variety of dork would actually wear one (hmm, they seem to be marketing it to obsessive sports fans). As Nathan Shumate observed, the wristphone was a non-starter, even though the necessary technology now exists and it was a perennial dream of futurists.
What are wrist-mounted devices actually good for? Displays that require no interaction, and convey little enough information that you can read them in a tiny format from some distance. That basically means a clock, with possible minor augmentations. I think the space has been pretty much explored.
