Concept phone with roll-up display

Ever looked at your hot new 3G handset with pride, only to be dismayed when it swings about in your pocket while taking a walk? If only this concept roll-up cellphone was real – bulky handsets would be a thing of the past. The flexible display and tight design offers an unprecedented level of portability when it comes to cellphones, but some people might find the keypad “roll” rather unconducive for typing during a hurry. Still, the advantages far outweigh its cons, so let’s just sit back and cross our fingers for some kind-hearted manufacturer to come up with a commercial version.
