Samsung trotted out a non-working prototype of the SPH-9000 UMPC in New York City today. It's a folding computer (did someone say... origami?) that will put all your attempts to attach a mobile keyboard to a PDA or cellphone to shame. The kicker is that it comes with a teensy weensy handset that piggybacks on the terminal's EV-DO/WiMax uplink. But there are as many questions as answers about this one.
