Ubuntu Linux is an open source (free) operating system for desktops and laptops. It has the same purpose as Windows 10 and Apple's Mac OS. For desktop/laptop applications, Ubuntu Linux, for me offers superior performance to Windows 10 and offers huge cost savings when compared to making the leap into the "everything Apple" world. Apple's proprietary equipment is usually multitudes more expensive than laptops and desktops which are designed to run Windows, and any Windows computer can be re-configured to run Ubuntu Linux. Ubuntu Linux add-on application programs are also open source (free) and are at least equally as functional (and often times superior) to their Windows counterparts. Most of the work products generated by Ubuntu Linux software are also fully compatible with Windows 10 or Apple/Mac users.
