Tiny screens

Many vendors (like Sharp ) are now releasing tiny (2 inches, 5 cms) screens.
Any geek can say wow, cool but what are they good for in a business environment?
Just a couple of ideas:

• Graphs. Everyone loves graphs and statistics. Think about a showroom with tiny stats screens(like sells or expected grow) embedded in the walls. Striking. Rember, you don't just have to be good, you have to be remarkable.
  
• Personal information: think about a creditcard size device you can lend to visitors at your building or at your congress, broadcasting tv streams with directions or ads on the next speech. Very sci-fi, isn't it?
• MMS: yes, short video messages. Image a network of tiny screens broadcasting short messages in a production or industrial environment, solving noise and communication problems in the assembly line.
