Lets change tot to ... "possible Apple car and possible VR". For the VR Part, why would an developer be interested in Apple VR while they all already with VR for years on the PC side. Apple missed the boat. The new iPhone is just a nother iPhone that looks almost the same as the one before.. ppl get bored. The OS is not that special either anymore in 2016. A lot of users are waiting for be next big thing where Apple will change the world, its not going to happen. I think Apple is going to shrink slightly in the near future. There iMacs will be sold.. no problem. As like there Macbooks.. no problem.. with tablets, much options for you on the market beside an expensive iPad. Same as for phones. There are many good phones out there, even better than the iPhone. The workstations are not with Apple anymore (never have been tho) and is controlled by Party's like Dell and HP. So, all they have left are the gimmicks, if you ask me.
I do enjoy my Apple eco system. But I would enjoy an Windows or Android eco system too. The name on the package is not so important anymore. But that is my personal point of view.
Thats because most OEM's have learned tricks from Apple and understood phenomenon on which Jobs built his Apple. Philosophy. Currently for Apple another big thing would be... changing itself in another direction as a company/business side. That would be biggest innovation Apple could do.
Computers are dying, PC's are dying. This is not only problem for Apple but whole industry. Thats why everybody is heading into "devices" rather than separate units, that account for idea of computing. Add to this picture Internet of Things, VR/AR, AI and you get where can Apple go with their business.
As for computers, more and more content will be consumed on consoles, smartphones, tablets. It is completely inevitable. Computers will mostly be bought by content creators. Progress however on desktop will slow down extremely, and only way to extract more power from hardware is scalability: multiple GPUs, multiple CPUs, etc.
Nobody will use 10 nm process for desktop parts, apart maybe small amount of Intel CPUs(low-powered CPUs), because of the nature of the process. We are stuck with 14/16 nm for at least upcoming 2 years, with mediocre upgrades to performance.
Why do I write this? Because it is not only Apple that is affected. Last stall in updates to their hardware and software was because IMO Apple prepares complete revamp of their hardware to celebrate 40th anniversary of Mac. What better way to do it is by revamping all of their hardware and software? Mac Mini, MacBook Pro, Mac Pro, MacBook Air, iMac, Final Cut Pro, Logic Pro.
