The Prestigio PMP3084B is based on an 8.4" (800x600) screen, and it runs Android v2.1 on a 700MHz Rockchip CPU. It has 4GB Flash, a SD card slot, Wifi, and an accelerometer. Format support includes:
- eBook Formats EPUB, PDF (DRM), TXT, FB2
- Audio Formats MP 3, AAC, WAV, OGG, WMA, LAC, APE
- Video Formats A VI, 3GP, MP4, RM, RMVB, FLV, MKV, MOV
The specs might not look like much, but I think it will be a cheap but decent Android tablet. I'm not so interested in it as an ereader, though, because none of the Android reading apps are designed to work well on such a large screen. But PDFs should be very good.
