Wiltronic sells a number of different products under the Iview brand: netbook, digital picture frame, a bunch of digital cameras, cellphone, and more. I only got to see the one ebook reader, but according to the website
Wiltronic will soon be selling 3 different models.
The one I saw was a rebranded Oaxis, which is made by Gajah International. Since the hardware specs are well known, I won't list them here. It felt quite solid and performed reasonably well. I can confirm that the reading software is FBReader, and that it has both a landscape and portrait mode. It doesn't appear to have all of FBReader's abilities, but the menu options include bookmark, search, goto page, and font size.
There are 2 page turn buttons on the left side of the screen, and on the right there are 12 buttons. When in landscape mode the two middle buttons can turn the page. I hope you can reassign some of the 12 buttons to turn the page while in portrait mode. Some users prefer one over the other.
It has a retail of $299 and a release date of soon. I'm not too happy about the price, but I see no reason not to recommend this as one of the ebook readers one might consider. It should suit someone.
