Whereas I used to think pen compuing was an inevitable evo of computing, after having a PDA for so many years, now a Treo and a tabletPC to go along with my 'normal' notebook. I see that computing will take on a more organic means of dispersion. I think that all of the afroementioned types of copmuting will play a part, with the issue being connectivitiy. That will be what become the computer, instead of the hardware, the software will be more the computer, with the hardware just how you are served to that connectivity.
Personal preference is digi ink for all apps, and a keyboard for those times when I just dont want to write. I like the idea of the 770. But would rather see it as a connected PalmOS PDA with Calligrapher
