I personally think that a lot can be done in the HMI area, and I'm not thinking about fancy UI's (we need them too, in order to sell devices), I'm thinking in 'breaking innovation', new forms of HMI, that can improve the interaction/experience with our mobile devices, that are nowadays part of our lives. An mobile phone is seen nowadays as an non intrusive device (there's only other 'piece' of technology, that we usually have with us, that has the same status), we really need to take more advantage of that .
