well to those of us, not using iPhone it is*
And to be honest, most of the files I sync, I never access on a phone anyway. So it would still be useful even without Android support.
Not sure how common my setup is, But I have desktop both at home and at work. And I use git and synching, to sync most of the stuff seamlessly. That said I mostly work from home nowadays, so I mostly use my work comp to speed up compilation, or run tests, dockers, databases, etc.
* Not trying to be an asshole. There are plenty of iPhone only app, that I sometimes** wish I could use, so I know how you feel.
** But not too much, otherwise I would switch by now :))
