I'd like to know how many "good" Android tablets are selling, and how much of this is the fact that Android has total dominance on the low end (< $99) market.

I'd like to know how many "good" Android tablets are selling, and how much of this is the fact that Android has total dominance on the low end (< $99) market. Specifically, I'd like to see market share for Android devices with Android 4.0+, 1GB RAM, and a decent multicore processor. I'm a happy Nexus 7 owner myself, but there are a lot of people with Android tablets that are total garbage.
