An interesting response to all the backlash I read was a simple question.
"Why don't you own a windows tablet that can do all the things a iPad can't?"
Simple answer, there all ****.
I suppose there will be android versions, but there's three reasons why they wont do so great against the iPad from the go:
1. Supported Content, (music, videos, books, apps, games etc.)
2. Publicity (for example my mum knows what an iPad is, but doesn't know what android is)
3. Brand
Basically you have to be a geek to get the Android version to be as good.
As much as i hate to say it, a normal consumer wants something "that just works" which is where the iPad wins.
