A lot of small businesses are reluctant to try Linux because they think it means moving away from Microsoft Windows, and you can’t blame them. Change is disruptive, and while a lot of software applications are cross-platform, most aren’t, so leaving Windows often means leaving favorite software behind.
However, the choice is not either-or, because the Linux world offers a lot of excellent tools for interoperability. You can mix Linux, Mac and Windows computers on your small business network. Then you have the best of all worlds.
