"I see. But why bother installing Linux, if all
computers come with Windows anyway?
"Well, not all computers come with Windows, although you might
get that impression browsing the shelves at your local computer
store. A growing number of hardware manufacturers bundle their
machines with Linux for at least two reasons: Linux helps them to
keep costs down and gives them more flexibility. Dell, HP, Lenovo,
Acer, and ASUSTek are just a few big computer manufacturers that
build and sell Linux-based computers. In fact, many innovative
machines like netbooks (e.g., ASUSTek Eee PC and Acer Aspire One)
and energy-efficient desktops like Linutop use Linux. Moreover, if
you buy a used computer, it may come with no system at all, so
instead of paying through the nose for a Windows license, you can
install Linux on it. Most Linux distros are available free of
charge, so you have nothing to lose.
"Free of charge?!
"Yes, free of charge. And before you ask, no, there is no catch.
Some companies that develop Linux distributions make money
elsewhere, for example offering support and selling Linux-based
solutions to big companies."
