I love concept gadgets because they don't need to conform to the reality of the tech world, you know, designing things that could actually exist. Instead, they focus completely on style and functionality, leaving the actual logistics of the device up to the eggheads in engineering.
Take this LG Touch concept, for example. It couples a slick, iPhone-like handheld with a big ol' dock with a fancy, glowing keyboard. The dock would act as a terminal for the phone, allowing you to use it as a mini-computer when not out and about. Sounds great! Now just invent it into reality and we'll be all set.
