Subscription model is not suited to everyone
After having used Deluxe Paint on an Amiga and then getting a PC, I discovered the wonders of Photoshop and have used it ever since; now, mostly for photography.
I worked in the video game sector for 10 years and many of the artists used Photoshop as they had "acquired" it when they were at school and taught themselves how to use it. Of-course the companies they went on to work for would spend the huge amounts of money required for all their employees to have Photoshop.
If Adobe insist on only having a subscription model, I expect things to change in the longer term. Kids of today will find a competitor's product which does what they need and will use that instead. When they grow up, they may no longer have Photoshop skills required in the corporate world and either companies will have to pay for training, or switch to a cheaper product. I know which I'd prefer!
Take, for example Pixelmator for OS X, it's just £22 to own, from the App Store, getting rave reviews and some professionals are starting to use it too. I think Adobe should watch their backs!
