Since the announcements of the iPhone and Microsoft’s Surface (both in 2007), an especially large number of people have asked me about multi-touch. The reason is largely because they know that I have been involved in the topic for a number of years. The problem is, I can’t take the time to give a detailed reply to each question. So I have done the next best thing (I hope). That is, start compiling my would-be answer in this document. The assumption is that ultimately it is less work to give one reasonable answer than many unsatisfactory ones.
