Earlier quoted context omitted.
That was 10 years ago. Yes, I also started using it because of that. These days the the more important feature (at least for me) is being able to offload rarely used files from my drive. SSDs in MacBooks are still crazy expensive.

When you click to open such file or folder, it will immediately download back to your disk and you can use it again. You will lose maybe a few seconds once in a blue moon when you need one of them. But you easily gain hundreds of gigabytes of space on your SSD. Just yesterday I right-clicked some folders to mark them "online only" and immediately gained +300GB free space..
Plus of course you can access those files from your phone or ipad too, when needed. Basically I personally have all my work files in Dropbox and don't use additional backup (used Backblaze in the past).
