Of course I was assuming in my "train schedule" example that the information was NOT on the net. There are lots of examples where needed visual information is not on the net, choose one.

If there were an infinite variety of information sources in our everyday life then it might be useful to choose a few that one would specialize in and then purchase a device limited to one information-type for each of those sources. Otherwise, one might find a device with thousands of sensors (e.g., a camera is a sensor, so is a radio antenna or a microphone), none of which are useful to that person.

But there aren't that many different sources that are important to us. That means that feature creep is finite -- look at MS Word -- it has had no major new features in years. It also means that adding a camera isn't a slippery-slope leading to a 2 kilogram device.

There are just a handful of information streams that are important, but they are all very important in that they can be used to improve/optimize our lives. Now someone may pick one or another and choose not to benefit from its use, but does that mean the rest of the world should also do without its benefit?

That is a pragmatic argument; naming the device "Internet Tablet" and defining that things of that name leave out this or that benefit doesn't really prove anything. If the name "Internet Tablet" were to be definitively accepted as having the meaning "doesn't have a camera" Nokia would respond to pragmatics, as any market-driven entity does, and change the name to something else. I suspect that the name was chosen to highlight the extra benefit that the 770 has over, say, a Treo, rather than to enforce a limitation on future enhancements.

As far as weight goes, as long as you also carry a phone and/or a separate camera you also carry an extra processor, screen, DSP, speaker, microphone, antenna, battery, charger, etc. In other words, including the essential information sources in a single device decreases rather than increases size and weight. And I AM a size/weight hound. I am annoyed that the 770 weighs as much as it does -- it drags in my pant pockets and I find it goofy that the cover weighs 2.5 oz!; I want smaller AND better, and in today's world, that is not only possible, but inevitable! My first camera phone was smaller and lighter than my previous non-camera phone.
