I have SL and it works, and it works a bit better then my other option which is a point to point wireless which I used for over 20 years before SL.
However I am not that impressed with it while it does work it's certainly not the best thing since sliced bread.
My wife is still working and she works from home using a VPN that her employer requires, it will drop out and loss connection several times a day almost every day.

Maybe the phone company where you are but not around here.
Still lots of buried and overhead copper cables in use and being worked on daily because of complaints.
I ended up dropping mine over 10 years ago as it was unusable.
Also no DSL as we are to far out from the "hubs" it only extended almost 3 miles from town.
