You left out simple web browsing and opera mini, flip camera phones, texting, simpler apps, BlackBerries and more. Much of smartphone technology was dependent on faster data connections and processor speeds.
My post was obviously a little tongue in cheek.
Yeh we had sms from the early 90's, potato cameras, and unbearably bad browsers coupled with slow internet (chicken and the egg problem, smartphone adoption was the cause for quicker high speed network coverage). Phones that flip, woohoo, the Startac was the first and last innovative device of that era. Blackberries were the first real push into making substantial changes like mobile email and bbm but didn't really go mainstream until around 2006/07 IINM. And then overnight all the tech that was already possible sprung up, but the phones were unrecognizable in almost every single way compared to the old generation.
