Photoshop :: CS6 - Head In Cloud(s)?

I was checking out the CS6 product page, especially wanting to see the uprgrade pricing (I currently own CS4 Design Premium full suite). I had not really investigated the Creative Cloud thing before, so I went through the FAQs. I'm still not sure if I want to go that route, or stick with the perpetual license thing.
 
You are assured of always having the most up-to-date versions, and can add any app at any time. I currently use Photoshop and Illustrator way more than the rest of the apps in my suite, but it is nice the rest are there when I need them. Who knows, I might really get into Premeir Pro or Audition.
 
The Cloud basically offers everything in the CS Master Collection. The question is, "Is it a good value (for me) (or you)?" It seems it's a better deal the more apps you use. In my case, comparing the cost of an upgrade to the Master Collection (which I likely wouldn't buy otherwise) would give me 2 3/4 years of the funtionality for the same price. Pretty good, even considering Adobe's new 24-month release cycle.
 
But compared with the Web and Design Premium upgrade, which would be the version I probably would buy, it drops down to less than two years functionality. But, I would gain the ability to add apps as my needs may change.The fact that you have to keep on paying to continue to use it is a definite turn-off, but not that much worse than the new one-version-back upgrade policy.
 
So, I have more thinking to do before I make up my mind. I would like to hear thoughts from those who have decided, particularly from those who have decided to get Cloudy. What were the main things that led you to that decision? Or against it?
