I'm sorry, I really can't take a service seriously that can't even show me my file extensions in the web client. That combined with the horrible idea to release a Sharepoint client branded as "OneDrive for Business", the buggy clients integration in Windows 10, and the number of times they've changed messaging around "unlimited" storage... I don't see any reason to trust OneDrive with my data.

Oh and there's the nonsense "magic" it does with OneNote notebooks. In fact, I'm pretty sure I accidentally deleted a OneNote notebook earlier today when scrolling through my OD account with the Mac client.

My one issue with OneDrive when I tried it (late last year) was that it was very CPU-heavy compared to Dropbox. It noticeably slowed boot times, and syncing large changes slowed the whole system down for the duration. There might have been other factors at play here, but I've since disabled it on my Windows install and only use Dropbox, and I don't ever notice it's there.

I switched from OneDrive to Dropbox this year - was loyal to OneDrive since it was WL Mesh. Dropbox made a world of difference. No more duplicates, and so much easier to reorganize files.

I used both Dropbox and OneDrive SDK, and from engineering perspective, Dropbox wins BIG. OneDrive sucks.

One drive doesn't offer near the convenience or integration. I've used various incantations over the year from the initial skydrive through to its relaunch and then the latest version but each time I have been let down by unusual syncing behaviour or some level of strange complexity (the worst requiring re-syncing everything)
