Well i think it's much better now but i still dislike the subscription thing the more i think about it as it has so many possible problems.
Maybe with that after you update for another 2 years then the price should be reduced and continue to do so each upgrade you buy. If the system stays with a subscription (which is basically what 2 years of updates is) then there should also be a reduced 1 years payment option.
A example of a major issue with subscriptions would be if someone pays for 2 years updates but then development slows down for whatever reason, as when they pay the update cost at that time it would be exactly the same product they had before so basically buying it again with no need to yet.
This is a major reason why i like the way regular +1 version updates work, i can actually decide if there is new features i actually want. With a subscription payment i would be wasting money on something i already had until a few months later or more when the developments had progressed to the point of making it worth the buy.
There is the bigger problem that after payment the development efforts could be spent on making features or exporters i would never need to use. Basically with a subscription you have no idea what will change, be developed or the focus of developments.
With major +1 releases though you don't have to guess and have the freedom to choose to upgrade or not if you think it's worth the cost. With a lot of software i own i have also had many free updates and sometimes more than a few years worth with no extra cost but when i pay again there is often a large price reduction so i am usually fine with upgrading.
Also with this idea people pay for everything grouped together. I am guessing some people will really like a iOS exporter but others might not have a iPhone etc and not even care about that yet they still pay exactly the same price. When they pay if lots of time is spent developing the iOS exporter or it's features and plugins etc then that's time and money lost for them yet they have no control over that.
