Successful Chromebook’s have always been the throwaway $200 models. Higher end ones like the Pixelbook served more as flagship devices to prove they could do more but were never really marketed.
I don’t think Google’s gonna make a souped up Chromebook because they know their place. They’re entirely internet dependent devices with little brand recognition and no serious software. The Neo serves somewhere in between that. They have the brand recognition and MacOS.
What software do you want to be considered serious? With the addition of Linux/Crostini, there's 3D modeling, CAD, and NLE video editing and compilers and everything else.
