Agreed, although where do you draw the line? Assuming you’re not living in poverty or a war zone is it acceptable to complain about anything? If your shiny new car gets keyed by the local sh1tbag should you just swallow it? “Never mind, at least I don’t have (insert terminal condition here)”? Of course you don’t. Everyone has a sliding scale of what constitutes a real concern or just irrelevant fluff.
I think you’re generally spot-on but like so many other posters seem to suggest that their Mac’s primary or indeed only use is Cubase. If your Mac is 100% for Cubase then you’d be daft to upgrade to El Capitan until Steinberg get their act together but lots have other equally as compelling and valid uses for their computers.
