Many youngs people waste a lot of time writing emoticons at the moment of chat in the computer [ =),=(,=| ] So, Pegadesign create a very small keyboard with only 40 characters that don´t need any combination to use it.  

It can use it only with 1 hand, foget about the SHIFT + 0 + 9, You can create a lot of emoticons with that keyboard, is easy to transport and it has a very cute design..

So… useful or not? only what I know is if they sell it a lot of people buy it.
