At the CeBIT 2010 technology tradeshow, Asus has unveiled the DR-900 - an e-Reader product that joins similar models from the company's technological rivals.

We know some information - it'll have a SiPix 9-inch e-paper touchscreen display, a profile about the thickness of a pencil, and connectivity options that include Wi-Fi and optional 3G. It'll have a battery life of about 10,000 pages and an auto-rotate function that allows you to choose exactly how you'd like to orient your device.

What we don't know, though, is what file formats it'll support, how much onboard storage it'll have, how much it'll cost, and when and where it'll be available. We've got in touch with Asus to ask all of those questions, and when we get a response we'll be sure to let you know.
