...So far I see subscription as more affordable way to get an expensive software even if it means paying more in the long term.
Except that with the "Creative Cloud" system it is not a more affordable way to get expensive software. The "affordable" model Adobe instituted and followed for at least two decades was the "upgrade" path. Make your initial investment in the software and then, over time, you can receive discounted upgrades and expansions, until ultimately, you have a full suite of software available to you at a substantial savings.
You could not possibly have missed Ladislav's point any more, which was it's a more affordable way to get into the software since there is no one time outlay for the first purchase... the monthly payment plan spreads out your total cost in even predictable amounts at regular intervals which is more manageable even though the total cost over a longer period of time is higher. Like leasing a car.
I haven't read every single post on this topic, but has anyone considered the tax benefit of the subscription model. If you make any money at all from photography, I presume you write off expenses. The monthly payments would be fully deductible each year.
The other thing I've noticed is many people are comparing the sum of monthly payments compared to upgrading at $199 every 24 months. First of all, the upgrade cycle was not always 24 months it was closer to 18-20 month on average I believe. Second, correct me if I'm wrong but wasn't it only the CS6 upgrade that was $199 and previous upgrade prices were around $300? Regardless of that, there is no certainty that if Adobe continued to sell boxed upgrades that it would have been $199 in the future, eventually the price would go up. So it's hard to say what the long term cost of maintaining a current version of PS would cost over the next 10 years.
