Re: The silver hockey puck works on and off the screen.
You sound a little unhinged to be honest, and a bit of a grumpy old fart. Windows 10 works fine. In fact, I really enjoy using it and much prefer it to Windows 7.
The whole point of touch and pen input on a big screen is so that you can input directly onto it. It's simply another form of input, but it doesn't remove any of the existing forms such as mouse or keyboard, so it's not like you're forced to use it.
If you really want an example of a device that is tiring to use, go and check out the iPad Pro, because that does not support mouse. You have no option but to use touch.
BTW, if you want a monitor which supports portrait, I'd recommend Dell.
