I decided to fully convert to Linux on my living room PC because I was convinced these random display drops I was getting were being caused by Windows. (I was right.)
I had a drive that I wanted to leave alone, because it had my videos and music and such. I wanted to try a new (to me) distro, so I just started using high rated ones I found on distro watch. The first two I tried (I honestly forget which) would NOT leave my video drive alone during installation (even with advanced options). The third one was MX, and it successfully installed while leaving my video drive alone. I liked that. I am used to xfce, and I like some of the custom little tweaks that MX adds to it, like easily making custom folder themes. I like that it can install .deb files and pretty much everything I've tried to run so far has worked.
So, yeah, that's why I like MX. I have since installed it on my laptop, my office PC, and my husband is dual booting it. It even runs his v-tube software, which blew us away. I know most of this isn't unique to MX, but it just seems to work really well for us.
Would be funnier if it didn't say "used" and only "junk."
