Ericsson also gave us the world's first smart phone, the R380. The R380 was the first device to come equipped with the Symbian operating system and had all the functionality most businesspeople would take for granted: email, WAP, PIM.
But aside from its innovative innards, this smart device was an interesting take on the traditional form factor. Like the T10 before it, the R380 had a flip-down element, although the R380 made the additional space more about functionality than form. By larding the flip-down section with buttons, it allowed the R380 to have additional screen size - a trick Sony Ericsson still uses on its business phones today.
