Honestly full linux desktop in a handheld form factor is pretty attractive.

One of the biggest pain points of linux laptops is getting the drivers right.

That being said The screen is quite small if you are dealing with text & while you can do some typing with the steam controller you won't want to do too much.

If your general set up is doing a tiny bit of work while away from a dock (with mouse + keyboard + monitor) and you dock it most of the time I think this could be a really nice package.
