I agree with you in principle, however as much as I've wanted to love OneDrive, I've found it to be exceptionally slow to upload in comparison and it still has the filesize limit of 2GB which is a showstopper for me.
In itself, OneDrive is a great deal but it just doesn't work for me.
Thats what makes having a dedicated T-1 line work so great for me to utilize.
It would drive me insane how it used to be so slow going through the normal channels of online movement options
