The network in the pocket

The day before yesterday I watched the movie "The holiday" with my gilfriend. It's about two girls making a holiday leaving their work, their friends and everybody else at home.
But though, they still leave their mobile and blackberry turned on.
Now imagine, making a holiday to leave everybody somewhere else but leaving your mobile on. Doesn't make sense, does it?
Ok, but everbody know, that movies usually don't claim to be logic.
What I thought, once again, is that in our modern world, we don't have to care about the place we are, we just have to care about the time it is. No, not even that. It doesn't matter what the time is because it's a different time depending on where you arem which timezone. So it's more interesting think in timespans than in points in time. Even more, what is a timespan, anyway?
One might think that 3 minutes is a timespan. But what the hell, who needs 3 minutes for something (despite the tea, of course). Perhaps we should start thinking in bytes we have transfered, perhaps in words we spoke, perhaps in something we ourselves think is good.
Ok, gotta go. We'll meet tomorrow, same time, same place (whatever this may mean).
