That's a 'what if' argument and is too negative. If you thought like that, you wouldn't leave your house - what if you get hit by a car, what if you have a heartattack, what if you crash your car? These are probably more likely than something you listed from Apple. People really need to live in the moment. In 10 years time from now, we won't be using the method that we use now to watch film. TV of today is very much the same as in the 1950s - a box and a screen - there's no feeling of being there, actually in the film/programme. There's no feel, touch, smell, physical experience - maybe in 10 years time, there will be a human connection and of course, today's platforms will be as obsolete as the betamax tape. I do hope that this evolves as IMO TV has not moved forward at all in terms of evolution. Maybe Apple will be dead as a company in 10 years time as the next generation brands will be here and Apple's subscription based ideas are hardly inspiring.
BUT...
I say live for today. Maybe next year i'll use an Android phone as i'm not happy with Apple's iPhone pricing structure and greed right now, but that's next year.
Also, you sound like a AV Enthusiast - this is your hobby. I appreciate that 100% but ripping discs, taking my valuable time and having external storage drives & IT does not in anyway make me happy or interest me. I have an Apple TV box in my beautiful lounge and that's all i'm prepared to put in there. I live for travel, the gym, fitness, surfing, mountain biking, road biking, hiking, triathlon etc. If I stayed indoors to watch the TV for just one night, I'd be truly miserable. For me, I like my weekly film with friends where we eat beautiful food, talk, laugh and enjoy the film - that's it for me and streaming / iTunes fits in with my lifestyle very well plus I can watch it whilst travelling on my iPhone or MacBook - that's just as important as watching it on the big screen for me. (Plus as an environmentalist, not having to ever buy discs with their plastic, transportation, logistics etc etc is highly important to me).
