Thanks to Google Docs and video Hangouts it's gotten a lot better than it used to be when I first joined the industry a decade ago. You're right though, it's still not as good as being physically co-present in a conference room, or sitting side-by-side at a computer. I suspect it will get better with VR. For now, though, I definitely enjoy working in an office with my coworkers the most, with perhaps a very occasional work-from-home day (only 5% of all work days) thrown in as a sort of quasi-vacation.
