The review is at PCPop [Google Translate].
The Onda V975i is an iPad Air clone with a 9.7-inch Retina-class screen, a 64-bit Intel Atom Z3735D CPU with a typical frequency of 1.3GHz and a peak frequency of 1.8GHz, 2GBs of RAM, 32GBs of internal storage, microSD card slot, micro-HDMI-out, 2MP front and 5MP back camera. It doesn’t have 3G.
There’s no surprise other than the quality of the camera (click to enlarge):
It doesn’t look very good, unlike the samples IMP3Net published.
There’s still no word on when the Windows 8.1 upgrade will be released for it.
