Apple may have thought about both, tried both, dismissed both, but both are good ideas if implemented the right way. Jeffrey Mincey:
On the Mac touchscreen:
Wait. What? Doesn’t that mean macOS Bakersfield or macOS Capistrano have to get a big makeover to handle touch? No. Windows 10 was an evolutionary product which brought some touch controls and basic touch options to a Windows environment. Nobody would use touch all the time on Windows 10 but it has its place, especially with the detachable keyboard models or the large screen desktop models which designers and graphic artists love.
On mouse support for iOS:
Many of us use Bluetooth keyboards on the iPad (less so on iPhone, of course, but using AirPlay on iPhone would make a TV a big screen, so that option could use mouse support to go with keyboard support). Apple even sells a Smart Keyboard for iPad Pro. Typing is how most of us non-designers and modest consumption creatures get work done on the iPad, so why not build in mouse pointer support to iOS?
Apple doesn’t seem to listen to customers until they start buying other products. Two words: ‘Mac Pro.’
