Much like moving emails to the cloud having your files available when ever and where ever is critical to a successful business. You can't move on the internet without seeing an advert for one service or another and the feature set all round is much the same. They all offer:
<ul>
	<li>File sharing (internal/external) invite others to view and edit content</li>
	<li>Backups</li>
	<li>Share large files securely (SSL) and easily, no one emails large files any more.</li>
	<li>Mobile access to all your data</li>
	<li>Post Comments and track file versions</li>
	<li>File access permissions</li>
	<li>Detailed reporting</li>
</ul>
Our tip when choosing a provider is to really think about the pricing structure. Some providers charge X amount per user/seat and give that user X amount of storage. Others give  you X amount of storage and an over the top number of users. It really depends on how much (in GB) data you plan to store. Saying that (and we digress a little here) if simply storing files is your plan then look at Amazon S3/Glacier

To link everything together you can seamlessly integrate and access content in other leading business applications like Google Apps, Salesforce, SharePoint etc. The ability to back up your data and store it in the cloud, then also automatically sync it across multiple devices, has radically changed the way we use computers, mobile phones, and other electronic devices for both personal and business use.
