In a previous post I've been looking at the Nokia 7650 which was released 10 years ago in 2002 and compared it to 2012 devices. Pretty amazing difference. But one can also go back 10 years from the 7650… and land back in 1992, when GSM was first launched. Flagship device of the day: The Siemens P1, have a look here. Now how many orders of magnitude is that?
The point I want to make here: The crazy evolution in mobile did not only happen in the past couple of years since smartphones have become mainstream, it's been happening for a couple of decades now, most people just don't remember anymore.
