Misto's demos relied on a few simple applications to prove its touch sensitivity. I moved puzzle pieces around the screen. I browsed through photos. I looked at houses I couldn't afford; Misto is currently in-use with at least one realtor although not available for general consumers.
While a coffee table interface would be fun for certain games, Misto's current version misses big by only recognizing one touch at a time. Sure, there are technical reasons why it and many other devices can't juggle multiple users. But for the table to have the social gaming applications HP mentioned, that untouchability is a major oversight. If Misto ever makes it to market -- perhaps for virtual/actual Settlers of Catan or other social board games -- it needs to accept two or more touches at a time before we want one.
