It's not only Nokia. I own a Sony Ericsson P910i smartphone, which has what can probably be described as one of the best and smartest one-finger-control-devices (I'm talking about the 5-way rocker wheel) ever invented for a phone. "Focus groups" told SE that the wheel was too complicated to use (which leads me to believe that at least that focus group was of simian origin, most likely chimpansees), so they dropped it on the P990 in "favour" of a 3-way rocker and two buttons. Suffize to say that that decision was not exactly applauded by the actual users of the phones and has in more than one case resulted in refusal to upgrade, or even total dropout of the SE camp. I now believe "focus group" may be a synonym for "drunks who happen to be stumbling by our office entrance today". That, or just apes...
