Did you know that Fujitsu had a modular phone with detachable keyboard?
Released in 2010 on NTT DoCoMo, Fujitsu's phone stood out with its 2-piece design. Yes, the phone actually consisted of two separable pieces, which were held together with a magnet and communicated via Bluetooth. The idea behind this unorthodox solution was to enable users to exchange messages via the device's touchscreen interface while talking on the phone using the keyboard piece. The keyboard could also be used as a gamepad. And before you say that the company could have built furher on its design, we must note that concepts of the F-04B were demonstrated attaching to a projector, a printer, and a scanner, all not much bigger than the handset itself. Yet these didn't materialize in commercial form.
Specs-wise, the Separate Keitai was a remarkable phone for its days. Its touchscreen had a 3.4-inch diagonal size, and a 12.2MP camera was found on its back. Its battery could last through a good 500 minutes of talk time or 2000 hours of stand-by. A smartphone it was not, but it had a few bells and whistles to justify its $660 price tag with, including the sensors that allowed it do double as a pedometer.
Unfortunately for its maker and carrier, the Fujutsu Separate Keitai didn't quite sell by the millions, or at least that's the assumption we can make on the fact that a successor didn't follow. Yet would you buy such a modular phone if you had the chance? Let us know in the comments!
