I was completely unimpressed. It seems they asked their phone customers what they wanted in a computer not asking their computer customers what they wanted.
Again, you don't use a Mac or any other Apple products, so what are you doing here making any negative comments about anything you don't use? TROLL!
I'm sticking with 10.9.5 on my MacBook Pro. I also have an older iMac, but haven't upgraded that either. I don't have an iPhone, or any other Apple devices to connect to, and don't plan on getting any. I don't use many of the application programs that came with this computer, like iMovie, iTunes, Garage Band, Face Time, etc. They can keep Siri. Who the hell wants to listen to that? When I upgraded to Mavericks, I had a few third party apps that the OS didn't like. I managed to get them to work, but don't want to be bothered again with any incompatibility issues. This OS works fine for me, and if it ain't broke...it don't need fixin'.
You assume that iPhone customers and Mac customers are two completely separate groups of people. They aren't. And with about 1.3 billion iPhones sold, that would seem to be the more promising growth market.
