Chromebooks aren't netbooks.
They're Android tablets with non-removable keyboards.
The idea of a netbook was very small, cheap, portable, full-featured computer that you could use like a normal computer.
All the ports, your desktop OS, and so on.
Chromebooks ain't it, even if they compete in the market segment that made netbooks a success.
I run my desktop OS on my Chromebook (boring Debian) and use it like a normal computer. All the ports (HDMI, usb) and so.
That sounds like an opinion baked in 2013 and never revisited. A modern chromebook with Crostini can run basically any Linux desktop stack you want. Like, what exactly are the tasks you need from a "computer that you could use like a normal computer" that you aren't getting today?
As a data point: I'm 100% converted personally. A Chromebook is what goes into my backpack and the device I use for all my general day-to-day UI clickery, and it's a better fit for my needs than Windows (not nearly as bad as it used to be but still sort of a PITA to make work as a Linux-focused dev environment) or Linux (not nearly as much of a PITA for a connected consumer network device but still has the occasional wart trying to get something weird to run).
So replace the OS: https://docs.mrchromebox.tech/
I've done that with mine. Worked great, and now I get around 30 hours of battery life with a lean linux distro, as long as I'm only like reading websites or writing on it.
