Ok, let's look at some groups here:
Full-time pros in good markets: You stay current on versions. CC is a great idea, it evens out the upgrade pricing, makes budgeting easier, good all around. A win.
Full-time pros in small markets: You typically skip versions, you might still be working with CS4 right now. CC becomes iffy, because it really will cost you more that what you previously spent. Purchasing a CS6 upgrade now might be a good solution, as you can keep using that as long as it runs on your OS.
Freelancers: Even tougher here, as you might be forced to subscribe if suddenly you can't open client files, and not having the option to upgrade when times are good is tough.
Photographers: You are stuck here as well, unless you use the rest of the CC package. Doing PS only is an option, but the price break isn't great, and you really only likely need the brush and clone tools in PS. Buying CS6 and staying there is a good idea, or finding other tools.
Hobbyists: Just find other tools, Adobe has now declared that you are not their market.
What it boils down to is that if you upgrade every version, CC works out OK for you, if you can use all the other software. If you skipped versions, CC is much more expensive than the previous upgrade.
Myself, I skipped from CS4 to CS5.5. I probably would have skipped again to CS7, but now I'll likely buy CS6, and stay there, for a long time.

It has to work out of the box, and right now it doesn't because this stupid Product Activation is in the way of the evaluation demo.
Buy CS6 now, or find alternatives.
