I think that's a little hopeful on the basis you can't really buy a used PC laptop and it'll be awesome. I've been trying to do that for 25 years and it has never been awesome. There was an inflection point around 2006 where a Linux desktop machine was usable and comparable to a windows or mac machine but they have since left it in the dust.

Linux didn't do a whole lot other than keep changing the UI and never finish it since 2006.

Have been doing the secondhand laptop+Linux for 15 years and I have never felt like I was missing out on OS features.

And while true circa 2006 (these Broadcom wifi cards...), I have not experienced compatibility/lack of drivers in ages.

I kind of did that with PowerBooks back in the days.

The hard truth was that used Thinkpads were a better option.

For the same price you could get 3 years old ThinkPads which were more powerful and in better condition than 6 years old PowerBooks.

But I did installed Gentoo on my PowerBooks G3 and G4 (it just took 2 days to compile Firefox). And ironically, this knowledge proved useful in my first job when I repurposed old IBM Power servers with it.
