whats the best Android tablet out at the moment.

I promised my sister I will buy her a tablet by Nov and from the looks of it the best by far is still Ipad and its really bugging me that I will have to dish out for an apple device.
I know better Android tablets are coming out next year but by then she would be an apple zombie sadly I would be the cause.

I have already lost one sibling to the disease just this month after not being able to convince her to get an Android phone instead of Iphone 4.
