Oh I misread the author's complaints about hardware as "software." Ok assuming the author hates liquid glass enough to switch cause of that, and doesn't have the same standard of polish for hardware, at least the post is self-consistent.
I don't believe the claims of Lenovo hardware (esp trackpad) being as good as a MacBook's, but he thinks it is, so up to him. The keyboard layout is annoying cause control-C is both copy and kill.
With the default terminal you copy by selecting, like X11, and paste with right-click.
So select is select or copy, right click is open menu or paste, both depending on whether or not you're in the terminal. Control-C is also copy or kill, and iirc shift-control-c is nothing or copy.
There's a meta key on the keyboard, idk why they can't just do meta-c meta-v everywhere. Same in Ubuntu.
