I once get told to buy a new laptop, see the specifications displayed as having Windows 10, but when booted up for test, surprise surprise, the installed OS was Ubuntu lmao
Unfortunately it was for a coworker, and they're not quite tech savvy, and thus requested for Windows...
I forgot, it's lesser known and maybe just a local brand, definitely not the big names like Lenovo, Acer, or Asus. It was cheap laptop, our workplace is stingy as hell
Ive seen that hp has custom Linux kernels on their support websites and I've seen news about dell selling laptops with Ubuntu. I've never bought one though.
