I do have Ubuntu on one laptop (in fact, it’s the one I’m using now). I’ve tried Debian, Mint Debian, Fedora, Puppy and a couple of others but settled on Mint.
Prism-break.org does not recommend Ubuntu as there are some data leaks but these can be fixed pretty simply. (That site is a great resource by the way.)
I will try to put a MINT variant on my USB and see how it looks and feels.
