The liabilities increased significantly only because Dropbox (as with nearly every other company in the United States) wanted to take advantage of the 0% interest rates that the federal reserve has kept.

Who wouldn't want to borrow $1.3 billion USD interest free or close to it? We need to take a close look and try to understand these numbers instead of just seeing "negative" = "bad"; more often than not it much more nuanced than that.

Sounds like a terrible idea right now. I think they are only popular here because of their association with YC. I honestly find Dropbox to be terrible and overpriced.

For simply keeping files synced between two computers, I thought Dropbox was the best.

Microsoft OneDrive is fuckin' awful in how long it takes for a file on one system to be synced to another, even when both systems are online at the same time. It also has a habit of completely pausing syncing entirely if it reaches a file it can't read (such as a lock file).

Google Drive works well, but I find its desktop client to be resource-heavy, especially on startup. I like its integration with my Android, though.
