This roll-up phone concept is a pretty interesting idea as you get to tote around an essential piece of technology without sacrificing too much space in your pocket. The keypad “roll” might be a tad irritating whenever you’re trying to key in a number quickly, but the pros (consisting of a flexible screen and compact design) far outweigh the cons. This is one touchscreen device that will receive plenty of love, but unfortunately it remains a concept until some cellphone manufacturer has the technology and guts to release one onto the mass market.
