I'm sorry 10.5 owners, you can dispute me as much as you wish, but those precious few inches really do transition the iPad from a "big iPhone" to something much deeper, much more immersive, and much more enjoyable than that.
Not sure why one would be sorry. ;-)
Being larger is an attractive feature to some and being smaller is an attractive feature to others. I think we should all be grateful to have the choice. And to be not so grateful to see the choice of a smaller option (mini) fade away...
