Last year I made a leap from my Creative Suite CS3 to the wonderful CS6. I only really use Photoshop, Illustrator, InDesign and Acrobat. But, the online suite for $29.99 a month gave me access to everything else Adobe I could possibly want.
Thing is, here it is almost a year later and I'm still studying and learning my four chosen tools. And, yes, now Adobe has come out with "CC" which is the planned future for their suite of tools - you sign up, they keep upgrading, you keep getting the latest and greatest.
They're already great. I can hardly stand it! I'm still trying to use all the cool things in CS6 and now I have so much more! The good news is that for over a year I've had the fear that my monthly fee would go up drastically when my year was up. Not so. With CC, since I already have CS6, I only have to pay $20 a month. An actual reduction. Who says big companies don't have a heart!
