Apple is my platform of choice these days. Full disclosure, I’m pretty well embedded in the Apple eco system and it’s been my consumer tech of choice for over 20 years.
I live in the UK and have recently cut the cord with Sky (for my non UK friends, Sky is essentially the equivalent of a cable service in the states), and I had a number of movies purchased through their store. Although I can still see those movies on an iPad, it’s not easy to watch them on a TV, so I’ve essentially lost those purchases.
In light of that experience, Apple feels the most future proof for me with Amazon Prime a close second.
I also recently “binned” most of my DVD/Blu Ray collection, but before doing so, I looked up what platforms they were available to stream/buy from. Out of just over 200 discs, Apple won with 122 available with Prime on 114.
Like a lot of people, I’ve done the full tour from Mosaic, through Mozilla and Phoenix/Firebird to Firefox and have spent much of the last quarter of a century in the Firefox fold. During that time I’ve also spent a fair time with one foot in the Safari camp and have occasionally checked in with Chrome (just to see what the fuss was about). A couple of years ago, I stumbled across Vivaldi and I realised recently that it’s sort of become my browser of choice. I love it’s customisation and speed and as OP said, it’s tab management is the best out there.
Sadly, it feels like were back in 2005 when IE ruled the roost and set the rules (very badly), and Chrome was the brave new world that was going to reclaim the web for the common man. Now we’re looking to Firefox to save the day. Maybe it will, maybe it won’t, but I honestly think there is genuine mileage in supporting projects like Vivaldi (whatever you may feel about Chromium), and let’s face it, it doesn’t take long to download a browser and check it out for a couple of hours.
