A question that will become increasingly important as more time passes is: how is not using that Creative Cloud working out for you? It's pretty easy to stick with CS6 at the moment, but sooner or later you will be using antiquated software that puts you at a competitive disadvantage. Since you are using CC, I presume you don't have a viable alternative to suggest, right?
The answer *can be simple, yet challenges your convenience...
I don't agree that such software is reason enough for being disadvantaged. The disadvantage you'll have with competition, is weak and low quality work.
One alternative available now is CorelDraw Suite X7, and I think Painter is a nice addition also. I have not used them in a long time, yet I own them and upgrade when I see it making sense. Till now I have Cs5 and it is working just fine so far.
There are other applications growing. There will be alternates. I hope this rental business model will collapse like a bad dream one day, as being the only option given. Hopefully we will see alternate software devs move closer together and vamp out such strongholds companies have, and limit the dominance from keeping users at their mercy. I have no close ties or affiliation to Adobe, or anyone, and I can comfortably have this personal view point. Certainly I can see the OPTION of such business models allow those that cannot otherwise afford the entry price benefit from it. But even then, there have been alternative options (students, educators, etc). And surely the CC model is advantageous for some users needs. Of course it doesn't apply to all users.
