I don't care what they call it, as long as they fix it. It works great most of the time, but occasionally on my surface I get a message like "40k of disk space needed" to open a 40k document. And it simply won't open. Sometimes on my laptop it won't save. And yes I have 45 gig of space on the device. Still using Google drive for most stuff.
