6 Years Ago

… when I wrote my first book, mobile phones where just that, phones. A small screen, black and white only, the processor running at a couple of megahertz and Java ME was a concept in the mind of some but not yet in many devices. And now look at what happened in little more than half a decade: Mobile phones with processors running at speeds beyond half a gigahertz, big color screens, touch sensitive displays, multi megapixel cameras, video recording functionality, GPS, Wi-Fi, etc. etc. Even very low end phones for a couple of Euros have a color screen these days. Not with a very high display resolution but 6 years ago, that would have been truly revolutionary. How quickly times change in the mobile industry!
