We’ve seen an iPhone case that gives your phone an E-ink screen on the back, but what about an E-ink smartphone? This device could cost as much as a ‘dumbphone’, but with all the capabilities of a 3G smartphone. There are definite pros to this gadget; one being price and the other being battery life. The E-ink smartphone would be much easier to read in the sunlight, too. The device might even be available by as soon as the end of this year.
