Creative cloud is an amazing service which in my opinion is worth every cent. It includes a lot of amazing programs so you can achieve every task with ease and precision. You won't regret subscribing.
I have been using CC for about a year now. I use Lightroom and Photoshop on fairly regular basis, as well as Dreamweaver and I've done a bit with Premier Pro and Audition, but I'm not too familiar with them and the features are so exhaustive that I sometimes get lost. I find the price to be very good because I'm using more than one and more than two of the products. For $600 a year I get all the software I can think of to do anything I want with photos, videos, web design, etc. and it's always up to date.
I have had zero problems with the software and the installs are quiet and well behaved. I'm a happy customer:)
Captivate in Creative Cloud
Creative Cloud is great, but include Captivate please! I pay two different subscriptions, one is only for Captivate.
Do Not Bother
Do not bother with this subscription based model which will just cause you headaches. I was traveling and did not have access to the internet on the day the CC software decided to phone home and disable the software that I am paying for! This subscription based model is going to bring Adobe to its knees and I can't wait. The only solution is to purchase or reinstall CS6 and find a different solution in a few years time! My trust and faith in Adobe is completely dead!
