General use? Not that I've noticed, everybody still considers the key component to be "and may never be released". Which is subjective, of course, but claiming iOS5 qualifies is ludicrous. Amazing what you'll make up just to tweak Mac users. Now, if you want a good Apple vaporware, try the white iPhone 4. (well, not anymore)Since both IOS5 and Icloud have been announced, but not released, they are vaporware according to general use of the term.
How about a better source?
