They don't.
It's very weird to think trillion dollar Apple get into any business to sell a few hundred thousand units.
It will be years before anybody can credibly call this a success or failure.
Apple Watch was very slow to take off. The iPad before it wasn’t a boom in the launch.
Tim Cook’s ultimate legacy will be does he drive AAPL into the ground by failing to innovate anywhere except this product? His AAPL gave people the MacBook with all the ports they wanted to their detriment. His AAPL failed in R&D to introduce anything new that was a winner. He did it all by taking everything from customers and the future and giving it all to shareholders. This Vision Pro is his chance to show he could create a vision for the future.
I don’t know whether it’s a major success without developers. And Apple doesn’t care much about its developers - and seems rather tone deaf with developers complaints. If Apple stopped being a bully, started listening to developers, stopped stealing from developers, and stopped stealing IP from small companies, it could be great. It could be bigger by not walling its garden.
I bought the Vision Pro for development. I want to see if what I have dreamt of doing is possible with it. If it is, I will guess that many developers will be successful with it and the long term will see us all with something like glasses that has a wireless battery pack SoC that fits in a pocket or purse and the glasses get lighter and better.
The brighter future will be when we just wear contacts or better yet laser in technology with our bodies. Sure hope there are no viruses!
I say we give it five years before we decide is it a success and truthfully it may take longer. I get that people are upset about the price, and right now it’s really just a toy without any apps or killer app to make it better than everything else. That’s what developers can do for AAPL, let’s see if Tim does the right thing by developers or if it takes world governments to keep forcing Apple to quit being the bully and make Apple treat developers, customers and its own employees better.
