Re: Would be even better

About the same as on any other mainstream x86 system. I.e. generally pretty well. (Not sure about BSD as I don't use it, but any modern GNU/Linux distro should be fine).
The problem with searching online for this stuff is that you naturally end up with page after page of all the problems people have because all the people who are just fine with it aren't posting about how fine it is.
Not sure what most GNU/Linux DE's are like with touchscreens, as a caveat. Lenovo sells laptops with these and I've never used KDE or GNOME on a touchscreen device. May well be fine - just thought I'd better qualify my answer.
