No, perhaps you should read my post above.
Or perhaps you shouldn't make assumptions about what other posters have read.
I'm under the impression that that is a reasonable upgrade schedule
You think there's only one "reasonable" upgrade schedule?
I have no idea what your talking about.
I'll make it real simple. I pointed out the stupidity of your remark about not buying all the upgrades meaning you don't have an intel version of the software.
Even if you were to buy ($600) and then upgrade ($200) ONCE in TEN YEARS, you will have had a cost of $6.66 per month for your software ($800 / 120).
Paying 50% more than that is supposed to be a good thing? And in all your calculations you assume $10 per month over all that time. The website makes it sound like that rate is only a promotional one for one year, presumably it's $19.99 after that which shifts the price comparisons way in favor of buying the software. And that's also ignoring that Adobe can raise their subscription price as well.
