Have a look at what came before Symbian : Psion series 5

In the end, when the Series 5 finally shipped, it was like being transported into the future, only through a very murky tunnel.

Gretton’s hardware clocked in at a meagre-sounding 18Mhz — but performed like a desktop Intel PC from just two years previously — and it could still maintain 30 hours use on two AA batteries. Once the circuitry was complete, the Series 5 performed the same tasks as its Windows CE rivals but used only a quarter of the power.

I still have two working Psion 5MX palmtops and love them to death.

Oh, maan… I still remember my 5800, I loved that phone to pieces… Excellent speaker system for the time (it was genuinely stereo and had a bit of meat on the sound, too!), my first touchscreen (which was a bit frustrating due to my thick logs, but worked perfectly with the stylus), and it was also my very first experience with multiplayer on a phone! Used to play that default racing game with a year mate in Uni, and it was very fun! And the OS was as an OS should be: so smooth as to not even register with the user!

Edit: oh, and the full QWERTY was very nice, although I was fresh off the keypad, so it was a bit awkward.
