You posted that you're paying $19/mth. at educational rates. Many don't have that luxury.
Actually, he said he got it for $15.99 at the Student/Teacher rate. Hell! For that price, I'd do it too. Except after that first year the price would skyrocket again to $50/month per license. Oh! And I'm not a student or a teacher.
Of course, pwhitehead is entitled to his opinion that those not purchasing CC are bull-headed, but he can't then make a case for others to spend $600/year when he's are only paying $202.
Is pwhitehead a student? If so, I understand his attitude. Kids these days think they know everything.
Is pwhitehead a teacher? If so, I feel sorry for his students being taught by someone who thinks software is the key to success.
Is pwhitehead not a student or teacher? Then he's still a baby designer coasting off his education until his eligibility expires, and his opinions lack the seasoning of experience.
For those of us engaged in the business of graphic design, the decision to purchase subscription software is more than a "Gee-whiz! I want the latest stuff" calculation. It involves evaluating the Cost vs. Benefit of the subscription. For those of us using only the big three (InDesign / Photoshop / Illustrator) a subscription of $600/license is a steep price to pay for incremental improvements, assorted bells and whistles, and multiple applications we'll never ever use.
I've been doing this stuff for over 35 years. I retired my waxer and non-photo blue pencils when publishing software arrived on the scene and I've seen it improve to the point now where most upgrades offer diminished returns for the same maximum investment. That's the real reason for the subscription model, I believe: there are no great technological leaps left to make that justify the lump price, but they can guarantee the same revenue stream by switching to subscriptions and offer small, incremental improvements to keep the whiny kids happy.
