Fujitsu concept phone

It's no surprise that the best designed and most advanced cell phone concepts are on display here at Ceatec in Japan, where mobile-phone culture is, for many, central to daily life.

This year, there are a bundle of elegant designs, some of which deconstruct the traditional cell phone form factor in very interesting ways. Take this Fujitsu design, whose screen and keyboard pulls apart to be used separately. It uses magnets to connect the two pieces in the desired configuration. NTT DoCoMo is demonstrating a similar concept.
