Upload & Sell: Off
Don't forget the CC subscription is a constant stream of revenue every year. The release of new versions of their products were on a more like 18 month or sometimes even more cycle, with a big influx of sales during the first part of a new release and then a drop in sales as the new release ages.
One thing that a company loves is a steady stream of revenue, day in day out....
That's not quite the case ... considering that Adobe went to the no more than one generation back upgrade policy ... users could no longer skip a cycle, if they did, they had to pay full price to upgrade ... then up until the May MAX announcement, their plan was to offer new perpetual versions of CS every 12 months, in fact more than a few users were fully expecting to buy CS7 only a year after CS6 was released ... yes, there was a tradition of 18 month cycles in the past ... but Adobe were planning otherwise before they decided to drop the perpetual model.
I agree ... software developers of any size would much more prefer a perpetual income over perpetual licensing ... the difficult part is convincing enough of their users it is also a good deal for them as well ...
Thus, when 4 out of 5 don't opt for the subscription model ... I can't see how they can match the historical revenue levels they are accustomed to.
