I was an OSNews writer/editor in the past, I followed the progress of smartphones closely. Here's a part from 2005 covering Cebit:
"Some highlights at the fair included some novel new consumer electronics being displayed, ranging from the very small to the ultra big! Such as for example Samsung's small 7 Megapixel Camera phone or their huge 102 inch Plasma TV! Further there was a clear converging trend to be seen with regard to hand-held devices as was already initiated more than half a decade ago in mainly Japan. Snapshot-camera, music player, GPS navigation and many other functionalities are finding their ways into the new generations of smart phones. And like was expected a few years ago the functionality border between 'phone enabled PDAs' and 'phones offering PDA functionality' is fading rapidly. The Japanese giant NTT DoCoMo was showcasing their 3G mobile phone services which are already widely in use in Japan, including videophone functionality, allowing live streaming video communications, or their FeliCa 'Mobile Wallet' service which allows instant payments and identifications."
