Depends on your major. I’m a bio/ecology major and a lot of the tools I used were cross platform or web based.
Also the university I went to did have basic Linux instructions for certain things like connecting to printers and connecting to the internet.
Yes but your mileage may vary. My pavilion x360 had okay out of the box support for it’s touchscreen. I don’t remember if tilt worked.
My touchscreen is currently busted and the hinges broke the case (and probably the digitizer) so I stopped using the convertible function of it.
