We all love our iPhones, but will it still represent the wave of the future in a few years? The one thing that I can’t bear without is some form of input device, better than a small touchscreen that is just unwieldy. I don’t think that the slide-away keyboards are a solution either. LG has been studying this quandary for some time and have come up with a solution: modular cell phones. Cell phones that have pieces that can be taken off and reattached.
