There seems to be an increasing number of doctors carrying around iPads for various reasons, one being that they can connect to the hospital's system to get patient information. Our hospital has free wireless.
I carry around a laptop for the same reason, and while I have considered getting some sort of tablet, so far it doesn't make sense. There are a number of things I can do on the laptop that would not be feasible with a tablet. I have some custom software, like a database for example, that I would have to find some substitute for, and really don't want to bother.
The overriding issue, though, is that I have begun to see connectivity in the same way I saw TV some time ago: a great way to waste a lot of time, and realize hours later that you haven't seen anything worth remembering and have accomplished nothing.
This isn't some abstract mental exercise. It comes from having one or more computers running in my house so that I can as often as I want step up to and look up something, browse for random information on selected sites, check out blogs, or whatever. In the end it's not any more interesting, mostly less interesting than flipping through the hundreds of channels I could see on my cable TV, and I've already decided TV is mostly a waste of time. If I lived alone, I probably wouldn't have cable, and maybe not even a TV at all.
Here we are, in the 21st century, bombarded with uninteresting stuff, much of it propped up with advertising dollars to get us to go out and buy something we'll be unhappy with after purchase.
