Very clever rant in the Guardian Online on the poor usability of the Samsung E900 phone. Cell phone providers would benefit immensely from halting development of "a bewildering array of unnecessary features aimed at idiots" and instead, building phones that compete to be the easiest for their target audience to use.
Perhaps the E900 is a great phone for teens, for example, but adults find it too complex. Don't give the complicated phones away to the wrong audience.
Some companies are working hard on cell phones with clear, usable interfaces. It's always going to be a huge design challenge to fit so many features into the small, stylish package customers seem to want.
