Here’s an app which really takes smartphones to the next level. Siri, which has taken a year to develop and required $24 million of investment through venture capital, offers the services of a personal assistant whilst on the move. I’ve yet to try it in the UK, but the demonstration video below certainly looks impressive – if you ignore the audible mouse clicks which seem to be navigating. I like how it draws upon a whole realm of internet information sites, such as OpenTable and RottenTomatoes, in order to improve user experience.
