Well, thing is. I refuse to rent software, plain and simple.
I don't rent other things like music or videos of things I want to keep, and use as I see fit. I buy CD's for my music, bluerays for the few videos I want to keep, etc.
I'll buy the last CS6 suite I can get.
These days, hardware is becoming quite cheap and powerful, and running things in VMs is so easy today....most people buy modern computers and barely ever strain the CPUs or utilize all their RAM or GPUs.
This isn't just about this Adobe change. I refuse to be a consumer in this fashion for any software.
I don't believe in renting software either (especially at those prices), so I'll probably go down the same path and buy the last boxed version of CS6.
The thing I do rent though, is music - but that's because it really does save me a small fortune. My premium monthly membership for Spotify costs me about half
the price of a new-release CD, and I'll listen to literally dozens of albums every month, on multiple devices. If I like a particular album a lot, I'll buy the CD (for the lossless audio quality and versatility of the format)...
