Believe it or not: The smartphone is 20 years old

The IBM Simon was rolled out on Nov. 23, 1992, at COMDEX, though it was code-named "Angler" at the time.

You likely couldn't have fit it in your pocket, given that it was about the size of today's Nexus 7, but then, at 18 ounces in weight, it probably would've made you walk funny anyway. It sported a 16MHz processor, 1MB of memory and 1MB of storage. Its operating system was a variant of DOS. Its external app ecosystem consisted of exactly one program -- a PC-to-Simon texting tool called DispatchIt, which cost $3,000 for the PC software and an additional $300 for every Simon client. To be fair, however, it could do some things modern smartphones can't, like accept fax transmissions. As primitive as Simon looks today, however, it was still recognizably a smartphone -- it used an app drawer, had touch-screen input (admittedly, in monochrome and with a stylus) and was even sold via the same subsidized pricing scheme commonly used today, at $900 with a new two-year deal from BellSouth Cellular
