Also being familiar with Linux, in Desktop Mode it's just a regular Linux PC, so with a bluetooth mouse & keyboard and a dock/monitor (and maybe a bigger hard drive) I genuinely think I could probably get away with just using it as my daily driver PC if I really had to.
I can attest to this. Went on a trip and used a Bluetooth keyboard and Desktop mode to get some minor work done at the hotel. Didn't even bother with a mouse, as the touchpads were good enough, though I did have a USB-C hub so I could plug-in USB drives. But the Web Browser, LibreOffice, and a VPN to my home/work networks let's a lot of stuff get done.
