This cellphone was invented with portable means of communication in mind, with an emphasis on the audio side. Now that keypads are getting better and the touchscreen is becoming a standard, we’ll have to face the fact that some people are more into texting and less into calling. Chatters will love the “Ultimate Chat Machine” concept, designed by Jin Woo Han for PPWK group & red-lab. The design comes in various shapes and sizes, however, they all have features in common. A sliding QWERTY keyboard and touchscreens. The Ultimate Chat Machine includes a rubber coating to help ensure the phone doesn’t slip from your hand and the key placement is ideal for hours of instant messaging and texting.
