It's funny. I questioned the iPad 2's not-so-smart cover a few days ago and got downvoted. I asked why people bother with it when it provides no coverage for the back. The response was 'dont lay it on its back then' 
I'd never not have a complete case covering my iPad. I'd be very disappointed if it got scratched! IMO a complete cover is the best option.
