For android it's a little more complicated. Not all android tablets are the same. I'd go with Asus Transformer (with dock = 16hours battery), Samsung Galaxy tablet etc. These are iPad rivals.
Certain androids aren't as strong. Nook, Archos. They will be slower and can cause frustration but they are great for their own purpose as e-reader tablet.
I think if you want simple, no setup and no hassles, go with iPad. Simple and easy to use. It's sort of like if you don't know how to build a computer, you might like iPad better, they did it for you. If you like building computers and knowing what software you put into it, that's what android is strong at.
