Here is a second video about this keyboard. I'm really thinking that if this keyboard is integrated in a body of a UMPC we probably are going to see many people interested on this. Just check how easy this young lady type! For instant messaging that will work very well and that's what teenagers love to do all time.
After posting this note I found that it's actually for sale already here. Being a new product with a learning curve I think that they are selling it at a wrong price.
