My mom has a business and mostly uses Windows and Mac OS X; I mentioned Linux because it could help save money.
She is unfamiliar with Linux though; I gave her some basic introduction (uncertain if it’s any good, but sure), but I would like to be able to ease her into Linux if she prefers it.
I wouldn’t mention it unless she had problems with either Windows or MacOS and expressed a desire to switch to something else.
She wants to try it, because she’s interested in saving money.
