screen resolution statistics for tablets

Is there any up-to-date resource?

I have been searching to no avail.

Yeah, just go to apple.com, look up the specs for the tablets there, then go over to amazon, look up the specs for the kindles, then head on over to barnes & noble, check out the specs for the nooks, then go on over to samsung.com, look up the specs there, repeat for any other tablets you want screen resolutions for.

Thank you, Fumigator.

Anyone, are there collective stats? Rather than information from individual resellers I need Android and IOS tablets active on the net, and - importantly - how the trends have evolved in the last, say, 18 months.

Something like http://www.w3schools.com/browsers/browsers_display.asp
but for tablets.
