Also, Apple has almost never been the first to do anything. Tim Cook even admitted this yesterday. What Apple brings to the table is an actual polished solution. Which having used Hololens extensively it absolutely is not.
Well, Apple has just released the 'smart keyboard' for its ipads, the 'smart' bit being that with a physical connection, "it doesn't need charging and automatically transfers data". Such innovation! Something keyboards have been lacking for decades...
I know I have been using thin and light portable keyboards that magnetically snap to my PC that also aligns the power/data connection since the early 80's
So you're saying the 'smart' bit is the magnets? Because I don't know what keyboards you were using, but the power and data connections were always aligned when I connected up my keyboards.
Unfortunately, the old-fashioned keyboards also worked when they weren't hard up against the screen - thank god we have these new 'smart' keyboards that have to lie flush against the screen to work.
