i know you’re not being too serious, but there’s great psychological difference to buying an updated version when you actually want (even though you may buy all updates eventually anyway), and having a recurring payment on your credit card. as long as not all daw manufacturers don’t jump on this bandwagon at once, or as long as your daw is not that exceptional and indispensable that you couldn’t switch to another, this is not a good idea imho.
as regards your ‘one has to have all the latest versions’; i know it wasn’t serious either, but for stability’s sake, i am now moving to an 11 years old version of sound forge, and actually went from 7 to 6 to cubase 5 for a certain project now that the lesser ram footprint of c5 makes easier to work with. it’s all horses for courses, and for serious projects, reliability comes before newer versions.
