Just letting you know (because I have been whinging about it for so long) that I've finally dumped Microsoft's Onedrive as my primary cloud storage facility, and signed up for a 1Tb Dropbox account.
Sure, Onedrive (which I still have access to, by virtue of my Office 365
subscription) gives me 10Tb for free, and Dropbox costs about $AUD120
per year, but at least it appears seamless, trouble-free and fast.
