iOS on tablets - Need a change in the OS

I think that Apple should do something about there OS for tablets. If they want to continue selling as good as they do now. Because it is just a big Iphone nothing else.
It need something like what Google has done with honeycomb. They need to use that ekstra space there is on a tablet, because they haven't done that so far, at least not as Google has done with honeycomb.
Write in the comments : what you think that Apple should do with its iOS on tablets.
