I've never had any illusions that Adobe had any great interest in me as a customer. I get it. I simply have never given them enough money to earn that.
I bought my first copy of Photoshop, a shrinkwrapped box of version 3.0, at substantial discount as a surplus item from a book publisher that had purchased more copies than it needed. I've since upgraded to every second or third version, and am currently using version CS4. My last version upgrade was four or five years ago, and cost approximately $150. That means my monthly costs for the current version have been approximately $30 per year, a far cry from the $50 per month it seems they will be be asking in the future.
To add some further insult to this injury, the only other Adobe product I use with any frequency is Illustrator, and for that I'm currently running version 8.0 (vintage 1999) on old Mac G4 running OS 9 classic. While I do some illustration for my work, the majority that I do is as a hobby. Therefore I cannot really justify even the cost of an upgrade version, and I'm simply comfortable with the Illustrator 8.0 interface.
With the subscription model, it seems Adobe's disinterest in me as a customer has escalated to outright contempt. I've used Adobe Camera Raw within Photoshop for several years. I'm sure Lightroom is a great product, but just haven't given it a long-term test drive. I've been working with Apple's Aperture for several months now as an extended trial, and I'm still somewhat on the fence as to whether I will stay with it long-term. However, the subscription model from Adobe makes it much less likely that Photoshop will be in my toolbox in the future. (If Lightroom remains available as a standalone app, I will certainly give it due consideration in the future.)
It has long been rumored that Apple has its own version of Photoshop waiting in the wings, just waiting for Adobe to tick it off enough to actually pull the trigger on it. While Adobe's subscription model does not seem to be an affront to Apple directly, it does seem to leave an open market opportunity for a Mac App Store product. What is certain is that I will be taking a very close look at applications such as Acorn, Pixelmator, and GraphicConverter to see how well these apps can replace the functionality of Photoshop that I commonly use. None of these are likely to replace Photoshop one-for-one as the graphics Swiss Army Knife, but I would rather jump back and forth between two or three narrower-focused apps that I actually *own* for the functionality I need than get roped into a monthly subscription for what is, to be honest, a rather bloated app at this point. (Admit it. The majority of us only use a fraction of Photoshop's full capability.)
Anger at Adobe is justified, I think. But once you cool down it might be a good opportunity to take a look around and see what other choices are out there for the particular type of work you do.
