Chromebooks (ChromeOS) runs on Linux, but it's limited. For example, my Chromebook is already Linux, but I have to enable the full Linux experience in the settings which allows me to run Debian alongside the ChromeOS distro.
Don't get me wrong, my current Chromebook is fine (if I had a reasonable amount of Chrome tabs opened), but when I enabled Linux so I can use the desktop version of Brave (and not the Android version of Brave) and run GIMP, it began being a little slower.
Also, every once in a while, Chrome will start downloading updates or the system would get randomly slow for no reason, making the CPU unable to handle a handful of tabs.
The upside of ChromeOS is that I can run most Android apps I use on it and play some Android games without needing a separate Android emulator.
The CPU is really the biggest limiting factor and I'm stuck on 4 gigs of ram, which is BS, but it is manageable considering I only use Chromebook for browsing the web. It's definitely a fast OS, but the hardware limitations suck ass.lol
