1992. I was 28 at the time and running my first incorporated business. Motorola 8000M, "The Brick". 403 650 5498. I paid $700 for the unit and the contract was eye-watering. Monthly bills were never under $400.
And it was worth every penny I spent on it...
I was the only one that could
receive calls from the drywall contractors I was working for and I got all of the work (or at least the first right of refusal) as a result of being accessible.
I have watched with great amusement as this whole thing has blown up over succeeding generations.
Last year I finally took the "plunge" and got a "smart phone", but I'm going back to an indestructible flip as soon as possible.

The "big brother" aspect of having a computer in your pocket is quite frankly?
Frightening.
All for this one, Ron
