For me it's the social aspect. I don't mean 'socializing' at work (although that also helps). I just mean avoiding isolation. Being physically distant from my team leads me to start feeling detached from them. But it's different strokes etc. I know myself well enough to know that I pull a lot of motivation from the sense of camaraderie I get by being in an office with people I like, so fully remote work is not for me. In fact, any more than one telecommute day per week is too much for me. Not everyone is like that.

So what I really wish for is increased flexibility.
