The Spanish ebookstore Luarna have added a brand new ereader to their shelf. The Avant XL is based on a 9" Sipix screen (16 level grayscale), and it has Wifi, 2GB Flash, a capacitive touchscreen, accelerometer, microSDHC card slot as well as broad ebook format support. Adobe DE DRM is also supported.
Retail is 399€.
This is actually the second ereader sold by Luarna that used AUO's Sipix screen. I'd bet that like the Avant, the Avant XL was designed by BenQ, an AUO subsidiary.
There's a full spec list at the link, but unfortunately it contains errors. The screen resolution is wrong, and the CPU is listed as 400MHz. That's rather low, and given the over all high quality of BenQ's other designs I have to assume the Avant XL has a better CPU than the one listed.
