I saw an article a few days ago where a guy who had purchased well over $10,000 worth of videos and music and games through iTunes somehow angered the god of Apple and had his AppleID shut down. As a result he lost access to all the digital content he had purchased, so of course he sued Apple. Apple is arguing that you really don't purchase digital content and that if you don't play by their rules they can shut off your access to it. Morals of the story: Don't anger the worm god that lives inside the Apple, and burn as many DVDs/BluRays as you can!
Joking aside, I rarely buy BluRays anymore, though I tend to get them as gifts from time to time. But of course now that I have a 4K TV it would be better to have a 4K BluRay player and 4K BluRay disks than the old HD model I have, but I haven't convinced myself it is worth shelling out $200 or more for one. But since I mostly buy digital downloaded files from Amazon and Apple, I can get those in 4K, if they or offered in 4K. Apple kindly updated all the HD purchases to 4K after they released the first ATV 4K box. Amazon however, is too cheap to do that. I guess Bezos is focusing on paying off his ex and regaining wealthiest person in the world status!
