That's exactly what I have with a convertible Chromebook. Super Snappy ChromeOS for web browsing. It can run Android apps, or stream them from my phone. Flip it around and it's a BIG tablet. 15.6" 4k screen. Going back into computer mode I can run full blown Linux, very quickly via Crouton or virtualized slightly less quick with official Crostini. Can also do a lot of the terminal stuff directly in the ChromeOS shell. In either Linux environment I can emulate Windows via QEMU/KVM. It's as fast as native in Crouton, again a bit slower in Crostini. Lightweight,long battery life, charges over USB-C will fast charge my phone and interfaces seamlessly with the phone for tethering that doesn't use hotspot data and doing messages notifications, etc.
