Once upon a time, I was known as Inspector Gadget. Why? Because I wore on my belt three different devices — a mobile phone, an iPod, and a Palm Pilot. The phone was only good for calls, the iPod could only play music, and the non-wireless Palm Pilot was simply a calendaring assistant.
I wondered then whether there could ever be convergence, such that at some point I only would need to carry around one device. Of course, that did happen, but the convergence occurred beyond my wildest dreams.
