there are two kind of users: the so-called “early adopters” who instantly install each new update – and the latecomers who wait a bit. one must also distinguish what an update it is, so for example security updates should always be made.
if a computer works well, there’s basically no reason to update to a newer operating system. here we recommend to wait and see what other users experience after that update and if it brings difficulties or bugs. it always has to be considered whether third-party software is used – these applications do not always offer the necessary drivers or updates for a new operating system so you might end up stranded with a non working software after an update.
