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.
Do all her applications run on Linux? If not, please don’t switch. She makes money with that. Money > ideology if you can’t afford losing it ;)
