Operating System Sucks
I have in my drawer the most annoying mobile phone I ever owned - the Samsung SGH D900. I can live with the less than impressive battery life, and the 3 Mp camera is quite nice, but the operating system for all its bells and whistles drives me nuts! It is just not intuitive once you have become used to the excellent Sony Ericsson OS. It just doesnt do what you would think it should, and there are always a few more keystrokes than there should be.
Pity - I liked the size and the camera and the synch is really good. But I got so frustrated I started throwing it at the wall!!
