Here's a nice image that sums up the entire history of the mobile phone, courtesy of NTT DoCoMo. It's so big that we couldn't fit the whole image above!
Japanese wireless company NTT DoCoMo is celebrating their 20th anniversary by putting together a physical exhibition consisting of more than 600 mobile phones released since 1987. Make sure to check it out if you are in Japan. If you aren't in the Land of the Rising Sun, you can check out the huge image (818 x 4,698 pixels) after the break. It's pretty interesting to see phones going from candy bar shapes with tiny screens to touchscreen slates with huge displays.
