instead we should have made them less terrible by not putting CPUs that can barely calculate what 1+1 is, giving them more RAM, and by not putting windows 7 starter on them
Key difference: netbooks didn't have locked boot loaders, did have ACPI, and could run any operating system. They were real computers, just small slow ones.
There are very small laptops today, but as far as I know, installing an operating system on them requires you to load an image of that operating system using a separate computer and proprietary software. A real computer can natively boot a storage device (USB stick etc) and install any unsigned OS from there.
A real computer also doesn't require you to ever boot the stock OS before installing a different one. That kind of setting belongs in BIOS setup, not the OS.
