Apple is a business, a business in transition. You only have to look at their earnings, look at the TV to see more and more that Apple is really concentrating on media and even including games, which I suggest we will see more and more diversification as Apple pursues increase its customer base by that diversity.
Apple can see the hordes of governments and countries wanting to control this and that, and where media production for most post is a revenue winner without the hassle of governments wanting to tell Apple how their computers and devices should be built or run.
Yes, I'm disappointed there's no new iMac, and for those who don't think there is space for an AIO, in my opinion the AIO is so cost competitive when you take everything into consideration and so tidy for home use and education it has a place in Apple's the line up for the foreseeable future as it brings Apple experience often to new users.
Of necessity they will of course still produce new devices, and I wouldn't discount a new 24in. iMac in the next few weeks, as it seems to be the 'insiders' get fed info, true and false, just to keep Apple on the menu, as well as a surprise announcement that may seem to wrong foot the 'insiders' just for the coverage and of late on MacRumour its been just the iPhone show, which for me an old timer in computing is really boring, but that's business.
