The iRex packs more features into a slightly larger device and supports more formats. Seeing as it has WiFi and can render HTML, I hope they include a web browser. E Ink will be perfectly adequate for mainly text-based pages, such as news sites or webmail. Animations or scrolling are not really essential anyway…

Note: iRex is a Philips spin-out. The first electronic ink ebook reader, the Librie, was a collaboration between Philips, Sony, and E Ink.
