There are two big differences.

The first is that you have access to all the Adobe desktop applications in the Master Collection and additional services like Typekit and Business Catalyst. Also the Adobe touch apps integrate directly with the creative cloud storage and website. You can see the list of things from here https://creative.adobe.com/apps. And here is a comparitive chart http://www.adobe.com/products/creativecloud/buying-guide.html.

The second thing you get is that we understand all of the Adobe file types. What I mean by that is you will get image renditions of files from products like InDesign, Illustrator and Photoshop. In fact you can navigate each page/spread of an InDesign file, or each art board of an Ilustrator file. With Photoshop files you can turn layers on and off. You get color swatch and fonts listed for files. All of this from the website. So someone without the Adobe desktop products installed can just view the files from the browser.

And of course more things are coming. You can read more here on this Adobe blog http://blogs.adobe.com/creativecloud/coming-soon-to-creative-cloud/.

Thanks John.

The line from the FAQ "Convert creative files to PDF to share them with clients and colleagues" reminded me there is more. You can download not just a PDF conversion of a file, but also an image file such as a png or jpg. Again this works great when sharing a file with someone who does not have that particular application installed.

With a free account you do get 2GB of storage with the renditions and metadata for Adobe file types. And as mentioned in the blog more features are coming to the browser. The 2GB storage and website features remain with the free account past the 30 day trial of the Adobe desktop products. This is a different value proposition than just more GB of free storage in the cloud.

I think the question has been answered based on the Cloud as it stands today - but it may not perhaps be the answer you're looking for.

If it's just free Cloud storage you want, use the other free services. That's not the point of the Cloud.

The Adobe Cloud primarily offers affordable monthly access to Adobe software.

Storage and collaboration are part of the Cloud but it's not trying to compete on storage or the other services alone.

The 1 month trial is really for you to evaluate the software rather than the storage space.

If the other free services are more attractive to you, go for them.
