Like I said, I love the choice it brings me - I don't have to work form home (I can use a coworking space for instance), but I get to decide every morning. I tend to go to a coworking space or to friends/friendly startups/friendly companies to hang out about one day a week, but it can be much more.
One tidbit: almost the whole company is remote (600 people!), so we're all organized around that, and it probably makes it easier.
So my personal take away: it's about the choice it gives you :)
