Awhile back we posted about the lack of simple phones now Motorola is looking at this market. See: Motorola’s Dumb Phone:
I don’t think these features are only desired in poor countries, but I am not basing that on any market research just my opinion. Complex devices with many points of failure (both technical failure and user inability to figure it out) should not be the only option. Simple, easy to use, reliable devices would have a big market. Creativity is not just about more complex devices.
