Fret not; when Sony released the first digital Mavica (the one that stored pictures on 1.44" floppys) I would have made a bet that digital photography will never take off.

My only lame excuse it that at this time it was just unfeasible imagining that one day in the not too distant future you'd be able to store terabytes of memory on a device the size of a thumbnail.

Still, not one of my best predictions.
