I find OneDrive extremely convenient, especially when working with multiple PCs. Example when working on my backup PC, I can simply drop a file in its OneDrive folder and access it from my main desktop.
When I was going to school, I could work on a project from my laptop, drop the files in its OneDrive folder and access them from my desktop without ever touching the laptop. Even more beautiful, is the app available to android devices so there's access there. For me, I find OneDrive so valuable that it's my top must have app.
BTW this is also coming from one who initially had "cloud" reservations back when OneDrive was formally known as SkyDrive. Once I started playing with the app and saw what it could do, I quickly got over my reservations and never looked back.
That's me.
