50 GB of free (promotional) cloud storage via Tresorit.

A new(ish) company called Tresorit is offering 50GB of free, super-secured cloud storage.  (I know, your first question is, is tresor a real word?  Tresor is a German word for vault or safe, not trésor, which would be French for treasure.  I'm assuming of course, that because German is the official minority language (second-most used language) in Hungary, and because this cloud storage is meant to be a secured vault, that the German word was intended.)

I'm actually excited because they use client-side 256-bit AES encryption and a couple other layers of security, so it's impractical -- for the time being -- for anyone to break into their servers and steal your data, then read it.  In fact, if you lose your password, there is no reset and no means to recover it, since they don't store that in some database server -- love that, actually, considering that many cloud companies have faced this problem including Dropbox and Evernote.  Now remember, there are easier ways to steal your data:

Someone could surreptitiously install a keylogger or use an open port for remote access via a trojan horse virus, then just sit back and watch all of your actions on your computer.

So, you could have the most secure cloud storage / sync service in the world, but if your computer is already compromised, it won't do you any good.

I know what you're thinking: Why bother?  Hey, free storage is free storage, especially when it's 50GB worth.  With the several layers of security built in, it's the perfect way to store the most important stuff you have, in the cloud: projects you're currently working on, your business records, etc.

Drawbacks: It's client-side software based, so no browser-based operation, and for the time being it's limited to Windows (no Mac and no mobile apps, yet).  The offer for 50GB free is only good until May 20th, and it's only available through that Lifehacker link or the GigaOm link (it's a download link for the Tresor Windows client).
