Best Cloud Storage

Mediafire

This is a classic file locker turned "legit" file hosting service after the megaupload.com fiasco. Recently they have also been trying to get into the whole Google Drive section of the market, online hosted file editing and creation, with support (right now) for Documents, text files, Spreadsheets and presentations.

Pros:

They offer a nice desktop client for all platforms (including Linux!) and give 50 GB free to start.

Cons:

No mobile client for the moment. Associated with seedy (punny!)  files. I've seen more than one person refuse to download anything from the site because it was Mediafire. Will stop downloads due to too much bandwidth usage.

Dropbox

Probably the most popular from what I've seen, has lots of good features.

Pros:

Features a cross platform client, for both desktop and mobile.  Makes getting more storage fun. For every 500MB of pictures uploaded from mobile they'll give you 500 more for up to 16 GB. But 500MB is A LOT of pictures. Respectable well known name.

Cons: 

Starts with a measly 2GB of storage space.

Box

Definitely the most professionally targeting, has well document APIs and many different subscription plans suitable for large corporations. 

Pros:

Sometimes offers awesome specials, like installing the Android app a month after launch gave you 50GB of storage for free! Starts with 5GB for free account and up from there. Also has mobile clients.

Cons: 

NO LINUX CLIENT.

Ubuntu One

From the popular Ubuntu operating system comes Ubuntu One cloud storage, which has features like streaming music from the cloud straight to your phone! (for paid accounts)

Pros:

Starts with 5GB. Also has feature to gain storage from friend sign up referrals. Linux support (obviously) along with Windows, there is no official one for Mac OS X but many unofficial. Mobile client.

Cons:

No Mac OS X support. Written using Qt so it stands out in comparison with the rest of the apps on a Ubuntu desktop
