This seems to rule out cheap android tablets.

Fairy snuff. Worth pointing out though, that more pixels require more
processing grunt, so battery life can suffer. Unless the device has a
large battery, which then makes it heavier/thicker of course...

Might be worth looking at the Nexus 10, simply becuase of the screen,
but it doesn't meet your requirement of an SD card slot.
One of the main reasons for me buying an ipad was the poor screens on
offer from Android devices as the time.
