... what makes Facetime different...
If
Ernst & Young believe FaceTime adds significant value to an existing product, then prior predictions of the value of that product may have been to low. Apple can be forced to change what they believed in the past to be the future (value.) This is a significant hassle. And stupid.
The $.99 is avoiding the problem of adding value to something, as Apple is charging for FT on Mac.
As Apple may choose what a "product" is, choose what the market have to pay, choose to view iOS and Mac as separate ... it should be possible to solve it differently if they really want.
The reason Apple had to do something does not have anything to do with reality. It is related to audit procedures, inflexibility and independence.
If the auditors belief and reality differ, either the earnings have to be restated (incorrectly) or some trick have to be invoked. That that is possible also shows that the ordeal is a little pointless. It also suggest that to relate earnings to intangibles isn't "accurate", but is there an alternative?
For some reason audits fail to detect even massive economic bubbles, even on a national scale. They fail to detect massive stupidity like the recent Nokia situation, it even seams like nobody knows that it has already happened, with Sendo, and Novell, and ohters (with MS smiling at and slaughtering the company). They fail to detect blatant fraud like The SCO group, that have yet to show ANY evidence, a fraud that drained money from Novell prior to the slaughter. Audits and certifications may provide some common rules, some standardized way to value everything, and be a motivation for management to think. I just have a doubt that it is able to more than nit picking. I hope I'm wrong.
I believe that this trick harm Apple.
I assume they have considered other alternatives.
