Linux Mint (on an old Inspiron 5530, currently chained to the ground) and the cheapest Ideapad (for travel) works for me. Perhaps there were one or two issues at the beginning? If there were I can't remember. I can keep identical installs on both which means stuff that worked at home will likely work on the road. Mint installation is so straightforward now that, personal data aside, I can consider install almost throwaway - it's just not a big step anymore.

As for the RPi I wish they'd make more effort for it to be a better kiosk or headless device - lack of built in safe shutdown makes me reach for arduino where possible. I don't anyone is going to use an RPi to replace their laptop or desktop anytime soon.
