In the same vein... I hardly take mine out more than once a month. If a majority of people do as I do I'll never see one.I work in IT at a University, and I would guess I see 1 or 2 every week.
But hey folks, Not seeing many iPads, is not statistically surprising at all.
Test it for yourself, and try this....
Randomly choose a specific model of a specific brand of laptop.
Now see how many of that specific model of laptop you see in the next month.
And how many iPads.
Which number is higher?
