Android is a cheap rip off and just doesn't work so smoothly. More importantly, the apps aren't locked down so there is little incentive to bring out the best apps for it.
That's completely wrong in my opinion, android for me on smartphones is way ahead of iOS and this is reflected in the fact that iOS sometimes "borrows" android features like the new notification bar etc. I've not experienced android on a tablet so I can't comment, there are some tablets with more hardware power than the ipad too so I don't think that's a failing either. Where it is let down is in the lack of music apps compared to those for iOS, which is very far ahead.
Windows 8 might change this, obviously being geared towards a tablet experience but we'll see.
