Here I am at this very moment languishing in a hot bath tweeting on my iPad.
I know, it's not a safe thing to do as far as the iPad is concerned but, it's doable.
It's the fact that a few years ago nobody would even have thought it possible to be connected 100% of the time anywhere and still go about doing the daily rigmaroles that we all do.
Unfortunately, or perhaps fortunately, we haven't got to the point where our tech can scrub our backs for us. Well, not side Japan I would hazard :-)
