All about the marketing. One reason Android Tablets don't fair so well against Apple is because of the way they are represented. Most of the time they aren't even on or plugged in, like employees don't even give a crap in the store.
While Apple has their products well marketed/displayed.
With ICS/Jelly Bean, and todays hardware, Android tablets are nice piece's of work. Looks like Google is getting the message and handling it's own destiny in regard to hardware and marketing.
