Why so pessimistic? I'm not a fan of Cook but they are moving in the right direction this time. Central TV app, and that touch bar seems to be a nice working idea, really improving the workflow, although it could be presented better. I could almost tell Cook is thinking about what Microsoft presented yesterday, he was kind of pensive today. Speaking of Macs the key thing they'll need to do now is to add touch support to Macs, that seems to be the future. They'll definitely need to do something with iMac and MacBook as well. I'll give them 1-2 more years, and see what they'll do with the iPhone 8.
Ironically, these 3D features, which Microsoft presented yesterday, Apple had years ago. QuickTime had support for 3D and VR since 90s, but it was dropped with transition to OS X.
Quicktime "VR" is to Windows 10 Creator Edition what the original Microsoft "Tablet" PCs are to iPads. They were right to dump that stuff. I cannot say that the Windows 10 3D stuff that I saw was much beyond a gimmick though. I almost fell asleep during that part of the keynote. We'll see what develops but I remain skeptical that anyone cares about 3D emails.
As for the touchbar, I think that app developers will ignore it and it will just become a defacto Function Bar key as usual. If this is what they thought the Macbook Pro needed, they really are out of touch.
