Anyway, while waiting on the platform at Peterborough I happened to spot the scene pictured here, Sara (I introduced myself afterwards!) perched on a yellow bin at the end of the platform, touch-typing like a dervish in her iPad.
13 months ago this scene would have been unthinkable, true very occasionally you might have seen a stressed-out salesman swearing at a battle-worn Thinkpad, but a smart, attractive female... much less likely.
Such is the change that iOS devices have sparked in our way of life, they're allowing us to fill every last minute of our lives with correspondence, media consumption and play (at least until the batteries run out) and what's more, for the first time, it's socially acceptable - even fashionable - to do so.
Whether this is a good thing I can't say for sure so I'll have to leave you to decide that, It's a long journey and I've got a film to watch and email to reply to...
