Changing hardware and software is just one angle of digital goods like books, movies, games, software, music, etc. When you buy digital goods, you are just buying a license to access that content. That's why there's always have a license agreement include that nobody reads. That agreement usually forbids you from sharing that good with others, but people obviously do that all the time. The license holder like Amazon, Google, etc. can legally revoke it at any time. IN the case of Amazon, they can legally delete Kindle books off your device.This is naive.
There is a lot of Windows software which only works with Windows XP and earlier Microsoft operating systems. New laptops do not have motherboards that are compatible with WinXP, and it's becoming increasingly difficult to find the older ones; most are in landfills by now.
What prevents computer manufacturers from making new models which won't execute the applications currently used to read digital text? Nothing at all; that sort of 'progress' happens all the time. I don't think people can buy a Windows Office Suite on CD anymore, they only sell digital downloads, with monthly or annual licensing fees. Every time Microsoft releases a new version of their software, that add some new features, and remove some others. Older software and operating systems were designed to obey the user's commands; newer ones tend to do most of the work and offering 'helpful suggestions', and the user is reduced to choosing from the options offered, rather than making their own decisions. This stifles creativity and original thought.
When more advanced text reading apps are created, many currently available titles won't be made available, and many others, like the Roald Dahl and James Bond books, will have been altered. Try comparing the text of The Holy Bible in any online version to a printed copy more than 50 years old - the two will be substantially different.
Interestingly enough, you can borrow digital books, magazines, etc. from most libraries these days.
