Windows 10 is not secure or private. Apple devices are. Linux devices are also.
If you are a new user to Apple or Linux, there is a big learning curve to use them.
If you are only doing writing and printing, those problems are greatly minimized.
Linux comes with Libre Office. You can try it for free on your present computer and see if you
like it first. If you are presently using MS Office, you can get a version for Apple computers.
