As much as I hate to say it, there is some serious logic here. Nokia is top dog for a very specific reason - usability.

Ever wonder why Nokia is the preferred mobile phone brand (at least in Asia and Europe, and second in the US)? It’s because of usability. Never mind those snazzy looks and features that other brands give you. Never mind the hacker-friendly mobiles that let users tweak and flash their firmwares to their hearts content.

Nokias rule because even the dummiest of dummies can operate them. Yes,the interface is usually clunky (like vertical-folder instead of grid like everyone else). But it works.

A Lesson in Design

It’s ironic that some devices that have what we perceive to be clunky interfaces are, in fact, those with the friendliest UIs–so friendly that many mobile users will simply not consider any other brand because they’re comfortable with a certain interface, and will stick to that…. Source: ForeverGeek
