If only Nokia had realised what they had by inventing the Smartphone, they might have got off their arse and designed their own operating system.... instead of paying Symbian no money at all for there's, and didn't it show.
Nokia should be the world leader in the mobile phone market now as well as back then. Idiots!
Symbian was theirs in the early days

And to be honest, they didn't really invent the smartphone, as the Nokia Communicator was far from smart, being a standard HP PDA using the modem in the Nokia phone. Although the definition of Smartphone is blurred - for most its a
mobile phone running an OS with an
openly published interfaces for 3rd parties to develop software to run on it.
Windows, Gooseberry, and possibly to a lesser extent Ericsson were the first with proper smartphones, although Gooseberry shied away from touchscreens for years, making it, basically, crap as a smartphone.
Windows ruled the roost of early Smartphones, until crApple came along and Andriod properly took off (Apple were the ones that inspired the majority to have more than just a phone).
