Since u r looking at the Onda, u may be interested in the following comparison:
Onda VI40 Elite Android 4.0 IPS vs Cube U9GT2 Tablet - Fight! | PRLog
The Cube seems to come out ahead for the 16gb ram, screen and battery but doesnt have hdmi out and costs US$50 more
Yes. I have considered the U9GT2 as well in the past. I don't care about the 16GB ram (there's 16GB version for Vi40E as well btw), The 10pt touch screens has slight advantage vs the 5pt, but I reckon the Vi40E had better screen contrast. Battery is one consideration, cost and hdmi is another.
But, my most concern is the CPU. Allwinner A10 claim to be 1.5Ghz, when it can only run stable on 1Ghz. The U9GT2 at 1.2Ghz has faster response. When a company lies about their products, it reflects bad on their products credibility and quality.
So, I may wait for a little while and see if the A10 chips are as good as they claim it to be. Anyway, it won't be shipped till early feb, So I may wait until mid Feb.
