We've been looking at wacky prototypes of rollable displays for so long that it's hard to believe they could ever get real. Polymer Vision, a Philips spin out, has just announced that it has its production facilities up and running and its first rollable displays have made it off the assembly line. And they're not leaving it at that. Polymer Vision's first product, the 3G-enabled Readius, is supposed to be available before the end of the year. That doesn't give them much time to slap the rest of the parts together, but hopefully the Readius can be giving Kindle some competition before we get too terribly accustomed to its DRM-ed ways.
