I develop and run code in Crostini (e.g. VSCode, primarily for TypeScript and Python development in NodeJS, run Postgres, etc.) Over the years the lack of performance options (i.e. memory and processor updates) has become hugely noticeable, e.g. compilation is much faster on my current MacBook.

The Pixelbook was always a bit slower (obviously running in Crostini takes a bit of a perf hit) but originally the other benefits made up for it, but now the performance gap has become a chasm.
