For business this is an attractive package. I work for a small newspaper and we run 20 or so machines with CS5.5, its nice you can get the whole suite and seen as tho every machine is used 5 days a week for 8 hours with these aps in constant use it is worth it.
Also for those thinking adobe will produce poor upgrades check out their youtube channel there are some awesome additions to CC only already like Camera Raw being a photoshop filter! http://www.youtube.com/user/PhotoshopTerry White's Top 5 Favorite Features for Photographers in Photoshop CC
If anything the photoshop CC seems to be willing customers with the new features as they aren't available anywhere else. Here in the UK it is £48 a month for the whole suite. Seems pretty reasonable, I am a graphic designer/photographer and I use 80% of the applications in the suite daily. At home I use PS ID IL LR and Muse. But I dont see the updates being slow or non existent I think it will speed it up to get more people on board. Once you buy the software they have you where they want you and the need for upgrades is less. Whereas with the CC they are reaching a broader audience.
Also it depends what version you are looking at. The Full CS6 suite in the UK is £2550. Now if you sign up to the CC it will cost £600 a year, each version of CS has had a shelf life of 18-24 months. For that time scale it will be £900 or £1200 thats half the price. Although the problem is that if you decide to quit then you have nothing for your money.
But at the same time I haven't been one to stay on older software, CS4 was slow CS5 was slow (on the mac side) CS5.5 64bit faster. CS4 wont work on Lion either so... IMO having the latest software to keep up with my kit is essential. Camera raw has moved on so far you are loosing out by not having the newest software especially in a competitive market such as print production.
So imo is depends on your situation. Really if you are an amateur a version of PS CS6 and lightroom 4 is a good combo but it will cost you more. But again it will be out of date in no time what so ever as CC takes hold.
But for amateurs I see this sucking pretty bad, there will be another option on its way. Early days yet.
I have full faith they will not isolate amateurs.
