I want an OS X tablet like the Suface Pro that can be a tablet or a docked laptop (with keyboard and trackpad). Why does Apple ignore this segment?
No you don’t want that.
OS X has both point and click AND MULTI-TOUCH just like iOS. The combination of hardware and software with OS X and Mac computers is optimized with huge trackpads that are multi-touch.
IOS is a smartphone operating system designed for meaty fingers.
Both operating systems serve their functions well, but not to be mixed.
My perspective is that an operating system would need to be created where itself and all of the Apps are responsive: one codebase, works on any device. This is a lot of work. I also view this future operating system as something much more fluid that gets out of the way and can work on multiple screens like a wall screen, desk-based screen, tablets, smartphones, desktops, etc.
Microsoft has the right idea with Windows 10 and devices like the Surface Pro, but the Surface Pro is a crappy laptop and a crappy tablet because it tries to be both and does neither as good as each category of device it purports to contend with.
So far, the best emodiment of what I’m envisioning is the Microsoft Surface Studio PC. That is like a future iMac. Apple cannot do this because of their dual operating systems. Down the road Apple will release a new OS and we’ll see what they develop at that time.
