I think we should all be entitled to our own opinions regarding different devices and their "usefulness" and "user-friendliness". We all have varying uses for the devices that we buy or want to buy and in the end, I don't see the point in expounding your preferences in an attempt to prove that you are somehow more "right" than the next guy. That being said, I'll say its hard for an OS to be both integrated AND expandable. Integration usually means closed development and $$$ whereas high expandability means open (sometimes glitchy) development and usually no $$$. To each his own.
