The user interface is not as intuitive as Dropbox's. Box, at least on the Mac, doesn't integrate es nicely as Dropbox. The web interface is very unintuitive and overstuffed with features as well.

At least that's my first impression of Box, when compared to Dropbox.

I don't know if they've fixed the issue, but the Box client used to spike CPU at 100% on OS X. This would occur when you have a folder hierarchy with a lot of small files in it.

It turned out that their client was enumerating folders and files looking for changed data rather than hooking into the OS X file system notifications. We really liked it for the corporate account since it's possible to selectively grant outside parties access to files/folders.
