I own Apple Logic and thus I'm grateful for the continuous updates. On the other hand, I'm mystified why Apple continues its investment in this audio program. Yes, when Steve Jobs bought Logic from Emagic in 2002, it made strategic sense to fortify Apple's "software portfolio" to make Mac hardware more attractive. But that was before the surprising massive success of iPhones in 2007. Now, it seems like sales of Logic…
I'm not familiar with Aperture. According to Wikipedia it and iPhotos were abandoned to the benefit of Photos. Not knowing why Apple made this choice, I don't know if doing something equivalent with Logic would make sense.
I do know Logic. It's a well respected DAW and some musicians do buy a Mac just to be able to use Logic. Also, DAWs take a long time term to learn well, so when the time comes for a Logic user to upgrade or replace an old machine, they'll probably buy a new Mac. (More convenient, less hassle.) All this of course helps Mac sales.
And while Mac sales might not be much these days compared to iPhone and iPad sales, the margins on Macs are still high, so why shouldn't Apple continue to sell Macs?
