Last time I tried it, I could never be sure when my files had synched. OneDrive would just spin in the background, not even using much CPU or network bandwidth, and with no indication of what the hell it was doing, while the file I just edited remained unsynched for hours.
For a product that wanted people to give it the entire content of their hard drives, OneDrive was woefully inadequate at handling large amounts of data. I ended up copying files manually to the device where I needed them to be, relegating OneDrive to the role of an eventually consistent backup.
When my (paid) subscription was up, I canceled it and never used it again. Now I'm much happier with a 1TB plan at SpiderOak.
Such a shame too since they have the best pricing AFAIK. I wish they would just buy Dropbox, integrate it into Windows in place of OneDrive, and call it a day.
True confession: I tend to cycle slowly through OSX, Linux, and Windows 8.1 because I like a little change. Similar to programming languages. My strange way to have fun :-)
