But I would also guess, based on the image at right, that I've had my hands on similar hardware. The Gobii Wifi looks awfully similar to the Aluratek Libre Touch, an ebook reader that I reviewed a few months back. The Libre Touch had decent hardware, but it was hampered by the outdated firmware. It was running Android v1.5 and that's so old that few apps support it.
But that was some time back, so there's a good chance that the Gobii Wifi is running on a later and more modern version of Android. That would be good; the Libre Touch had a nice vibe for a budget tablet. In any case, the Gobii Wifi is coming in early November with a retail of 1,299 rand (~ $163 USD). The price includes a 200 rand credit for the Kalahari.com ebookstore.
On a related note, the Gobii Wifi is actually Kalahari's second ereader. Back in August they released the Gobii Color, a basic 7" ebook reader. I've had my hands on that one as well (as the Aluratek Libre Color). It was decent but not spectacular.
