If anyone was going to improvise nunchaku, it would be Jackie Chan with Samsung's new SCH-W2013 flip phone (pictured). True, he looks like he's contemplating the beauty of the sun and not so much the best way to dislocate a person's kneecaps with a piece of consumer electronics, but that doesn't mean it didn't cross his mind. But enough with the JC — you came here to ogle a phone.
The specifications are really solid: two 3.7-inch, 800 x 480 super AMOLED screens; a quad-core 1.4GHz CPU (most likely a Exynos 4 Quad); 2GB RAM; 16GB of flash storage, expandable to 64GB via microSD; Android 4.0 and two cameras — a forward-facing 1.9MP and a rear 8MP one.
As for dimensions, it measures 60 x 117.2 x 16.83mm, putting it at roughly twice the thickness of the Galaxy S III (8.6mm) and iPhone 5 (7.6mm), though that's hardly surprising given the design.
Sad news is it appears only on Samsung's Chinese site, so there's no knowing if it'll see release elsewhere (or what the price might be), though Engadget speculates ~$US3000, which is... insane.
Until I got my iPhone 4, almost every phone I owned was a clamshell. There was something satisfying about snapping it shut after a call or checking a message, almost as though it was feeding my subconscious desire for an old-style Star Trek communicator or new-Trek tricorder. Not that it could scan alien lifeforms or initiate a beam ups, but that was the dream.
