Too inefficient to manage the 'ecosystem' products
Part of the Apple 'story' has been that you can buy a whole ecosystem of products where 'everything just works'
I have iMacs using Thunderbolt extra displays, macbook pro, apple tv, mac mini as a media centre, backing up to an Apple Time Machine.
Apple have completely given up on the wifi networking.
If they were innovating - they could be selling mesh network devices that extend the apple network around the house while offering airplay 2 speakers or Apple TV and Siri.
(assuming they decided to make Siri decent)
TimeMachine is fantastic - but suddenly more difficult now that I can't buy an apple device to back up to
No thunderbolt/cinema display is available any more
Mac Mini and Mac Pro have been abandoned for years (mac mini recently updated).
As they narrow the product range - they force people to connect with other ecosystems and lose their grip on the 'everything just works' story.
They are behaving like a small company that can't afford to manage a wide product range and needs to focus on a few core items.
That seems like a mistake to me.
