I don't understand any of this? You talked about old formats being redundant and then mentioned DVDs which have been redundant for at least 10 years. You don't have to transfer any past purchases over for 'new technology' - that's what iCloud and other systems of that nature are for. Nothing has ever been easier for online content in 2024 going into 2025.

Cloud, digital, streaming etc etc
In my him humble opinion far too much reliance placed on that nowadays- give me something tangible any day!
Books and magazines can be kept for years and I still have a seasons bound copy of programmes from the early 1950's and loads of magazines and programmes from years ago and nothing electric needed to look at them!- digital stuff so easily lost!

Digital stuff is not easily lost if you take care of it. Same as paper.
But you can make multiple copies of digital to safe guard it, and it is always in perfect condition.

Thanks PT you're obviously converted.
I'm not and lots out there are the same as me.
If it came to digital or conventional there's only one I'd buy.
