What makes the cloud really important to users, is when it’s employed as a backup. Why is that such a game changer? By backing up to the cloud, you have access to those files, from any computer you have associated with your cloud account. And because Linux powers the cloud, many services offer Linux tools.

A person needs the right tools for the job. There's nothing as frustrating as getting halfway through a car repair, for instance, only to discover you don't have the specialized tool you need to complete the job.
