Concept designs are awe-inspiring and I think noone should have a doubt about that after witnessing those most coveted concept phones earlier too. The latest in the line is Nvidia’s Quark smartphone that can be taken as a perfect blend of video iPod and iPhone. The smartphone brings a 3-inch touchscreen display, a 3-megapixel camera and is able to playback music and videos. The concept phone runs on a Nvidia GoForce 6100 chip. But as usual, most of the concept phones remain a concept only. Hope the Quark doesn’t see the same fate.
