Jealousy factor can't be beat. But beyond making your friends/acquaintances drool on social media, yes the ergonomics stink for classic development.

However, I think variety is nice. Just like in an office situation, sometimes a breakthrough idea comes when sitting alone in an uncomfortable meeting room (and without secondary monitors). At home, I do some work on my back deck (partially remote worker here) but it's only when I'm in that mental place where I need to crawl out of a box and get a fresh look on things. It's also nice during meetings, so long as you prevent outdoor audio from distracting the conference call.
