Look, I am among the ones that complain, I too want to keep the status quo (read: upgrade every second cycle), I hate Adobe for what they are doing, etc.
I am just pointing out the inevitable, that after the dust settles, most of us will adapt to the new reality, and that's what Adobe is counting on.
Who is to say that, if the subscription models succeeds, everyone won't switch to it ultimately? Microsoft, Google, Nik, Apple, etc. Shrink-wrapped software and perpetual licenses might go the way of floppy disks, betamax video and CD music. We will kick and scream along the way, but how many people do you see today with a Walkman?
To put things into a perspective, my housing association is currently forcing me to fork out close to $4K for deck maintenance on my modest townhouse (advertised at purchase as "maintenance free"). That comes to about $500 per year. I can assure you that Photoshop provides much more pleasure in my life than the damn deck.
