Apple has reinvented the wheel and it is square. If they want to improve on the age-old save paradigm fine - augment it. But don't remove a computing paradigm that has existed since time immemorial.
I give Lion a D- and consider it lamer, in effect, than Window ME and Vista combined. It is Cupertino Edsel!
Apple destroyed OS X IMO with its janky "Versions" debacle. Removing "Save" and "Save As" from the File menu makes Lion the most retarded version of OS X in history.
If Apple doesn't put File save features back in OS X I predict it will lose a major percentage of the share it picked up since Leopard... Deservedly so!
Since the object of marketing and advertising is to dupe consumers into believing a product is better than it actually is I'd say Amazon has a winner. I envision some ignorant consumers confusing Fires with iPads and therefore taking a minute share away from iPad.
