I actually switched to Ubuntu full-time way back in 2006 when I went back to school (anthro major), specifically to help me focus when using my computer and not get distracted by playing video games. Of course, nowadays with wine and proton on steam, that might not be as effective. But it worked well for me, never experienced any issues with word docs opening in libre office (or rather open office back then) or vice versa. There was once or twice where I had to use a computer in the lab in the library to run some niche program or another for an assignment, but not a big deal.
As a Minnesotan I’d like to point out that Walz really isn’t a progressive, however, like Biden, he’s repeatedly shown a willingness to welcome everyone to the table, and (generally) not stand in the way of progressive legislation, even when he personally doesn’t agree, so definitely not the worst choice. But I say double down on minority women, nominate lieutenant governor Peggy Flanagan instead, let’s get the first native woman in the White House!
