Am I the only one that literally never uses the touchscreen on my laptop?

The shortest answer -

Arch has really good documentation and a release style that works for a lot of people.

Ubuntu is coorporitized and less reliable Debian with features that many people dont need or want.

15 total days of paid time off may be average for people who actually get PTO, but most people I know only get paid when they come in to work - no PTO at all
