I've actually never heard/seen this. I had to go look it up and see what it was.

I don't think I would get it, unless it calls for it. My school provided us the entire newest suite for free. It seems interesting though and convenient. But, I'm not really all about the newest versions. I still prefer Photoshop CS4 over the CS6.

I usually only get newest versions if the newest update is helpful or needed. I shall see how long I last.
