I'm still doing a lot of reading on the concept of pervasive computing, aka ubiquitous computing, for the semi-project that I'm on. I say 'semi' because we've had two meetings and nothings happened yet along the lines of saying what our deliverable is. Anyway, the idea of PC or UC is cool. Leaving aside the people who want to tie it to everything, or treat it like the Holy Grail (the people at MIT's Media Lab come to mind), the idea of PC as a way to augment your natural abilities to communicate and retrieve information is intriguing. The idea incorporates things like tools that start when you want them to -- a given time, or a triggering event -- without you explicitly saying for them to do so, tools that are aware of where you are and where the resources you want are, so that you can tell them to act on a resource without actually knowing much about the resource or where it is, and tools that are connected to each other, which are not now, so that they can share information -- your personal organizer talks to the car computer, cell phone talks to the address book in the car, point and click sends document to address in email address book. I'm trying hard to 'see' this functionality in the environment that I work in and that our customers work in. Its challenging because, of course, we tend to accept things as they are; the limits seem natural.
