The ground does not freeze that deep until you get to very northern latitudes but yea you do need the space for horizontal loops which not everyone is going to have.

Ground loops just have to be a bit under the frost line, more like 3 meters deep than 30

I've been on Linux for a while and at this point must people use their computers as glorified thin clients for Chrome.

This has made Linux way more viable as a day to day OS. Valve is working very hard to make games viable and is seeing some success.

The major blind spots remain industry specific software outside of software dev. Things like Adobe suite and Microsoft office for example. They often have a Linux equivalent but it rarely fits well into industry standard work flows.
