There's one thing I really like, and that some people might not know about, in the new CC edition.
With the standalone software installations like CS6, you can only install on two machines. With the new cloud-based software, you can install on as many machines as you like; but you must be signed in to your Adobe account in order to use the software and you can only be signed in on two computers.
This makes the whole thing much more convenient for people like me, who may use one or two machines nearly all the time but may need to use the software on one or two additional machines on occasion. All you need to do is sign out from one or both of the machine you regularly use, and then sign in on the machine you want to use this time, and Bob's your uncle.
