You're probably wondering what's been happening with that super thin, super sexy Plastic Logic e-book reader that we've seen floating around various tradeshows. Well, the device has landed at D7, and it's got a few new features cooked up -- most notably, built-in 3G data. There's no specifics on what carriers or bands, but besides that WiFi connectivity, you'll be able to go totally nuts out in the real world. Additionally, it looks like the company has seriously tweaked the UI, now providing a simple and clear interface for getting around your documents, and a page-turning gesture (don't mind the green tint in the pic above, the screen is still very much grayscale). The slate is definitely lust-worthy, but we noted a fairly slow screen refresh (way slower than the Kindle), which is kind of a downer -- along with that fairly distant 2010 launch date. Plastic Logic also made an appearance on Fox Business News today, and the video is embedded after the break.
