[I am surprised that neither Samsung nor Apple have gotten the idea of an '8' inch tablet. Should be a killer in the Chinese market !]
That's because in the China market, there is already too may 8" or 8.88" me-too Android tablet clones that are 100% made in China. It is way beyond saturated. 🙂
A 1280x800 IPS 10" tablet that has 7 hours battey life sells for $199, complete with microSD, HDMI etc all sort of expansion slots. The competition is way beyond crazy over there. (But still there are people who will line up for iPad, go figure)
