With the creative cloud subscription, you can install the software on 2 different machines as long as your basically just using one at time. It is talked about on the Adobe help pages.
For example, I have the subscription, and up until recently was using a Windows 7 PC. I’ve just changed to a Mac, went to the Adobe site, logged in and downloaded CS6 stuff onto the iMac. No questions assked other than logging in to begin with.
I could swap between using the software on either machine and it never questioned it.
If you can get the education pricing for creative cloud, its a brilliant deal imho. I think its £22 / month for me.
