Early versions of Amber’s “scroll-screen” we described in In the Shadow of Ares are close to being reality, as LG has announced plans to mass produce the flexible “E-Ink” eReader.
Advantages of flexible displays include lower weight, lower power consumption, and increased durability–they won’t shatter if dropped. However, early incarnations are likely to have some limitations versus current eReaders: they are likely to be slower, monochrome, and not suitable for video.
Sounds kinda like the original eReaders of just a couple of years ago.
