3) Is not true for me though, it's awful mostly, but that's my pet peeve (all coders assume everyone else is on a 1000mbit connection as well all the time) and MS is really bad at making anything work on bad connections. Office 365 isn't even getting past the 'wait while loading' while Google drive/docs is completely usable when I have a bad connection (which is often). The software that was written for bad connections, like Whatsapp and Wechat, for me, have much better quality. But no video (which I personally don't need, but it violates your 3rd demand).
