Technology is definitely not what it used to be. Twenty years ago, we could buy a laptop and everything would work pretty much the same for over a decade.
For example, when you switch on an old Windows XP machine (which is, by the way, no longer supported by Microsoft) and any installed Word and Excel software will be there just as we left them, still available for your document and spreadsheeting needs.
If we want to play some old computer games, there’s an argument that an old machine or operating system will be a better choice to play on as a newer machine will run the game too fast, or be incompatible and not run it at all.
But the world of technology has changed in the last ten years or so. More and more apps need a network connection to operate, or take advantage of new features in the software or hardware that didn’t previously exist such as augmented reality, so they need a new device to work.
