Sure, and I'll try to be brief.
I was selling cellphones right out of university in 1986, when they were $5,000 and the size of a suitcase. You know, when they dropped down to below $1,000, more people started to buy them.
The one thing I remember saying to everybody when I was making a sales pitch was, “I'm going to work hard to convince you that your productivity is going to increase with this phone, but the minute you have it and you use it for a day, you'll wonder how you survived without it”. That's the reality: every new form of technology increases our productivity.
My wife used to say to me, “It bothers me that you use the BlackBerry when you come home”, and I said, “Well, then, I can stay at the office longer, if that would make you happier”.
