Amoled screen is better used with movies than with web browsing. So why make it 4:3?? 16:10 is the best ratio.
4:3 is not that good for books , books are closer to 3:2 , also books are using margins, tablets need less of them because bezels play this role so even a 16:10 would be better aspect ratio than the squarish 4:3.
I find microsoft's 3:2 being the best. Best for sur
