You have summarized the good experiences I have had working from home (except onsite for a while at Google and Capital One) since my wife and I moved to a small town in the mountains of Central Arizona in 1998.

I have two areas of my yard where I can work, one is always shady, I have a dedicated office, but also work in the living room and kitchen table. I have a nice external monitor on my desk, but I don’t really need it for most writing or work tasks.
