 -- Ease of bug reporting and logging.
 On Windows, you can (sometimes) use Ctrl-C when an error window pops up to copy the error message.
 On Linux, you can attach gdb to a running process, start a logfile that catches all output to stderr, and run a backtrace when the program fails.
+Or you can attach strace and see what system calls it makes.
+There are similar programs for Windows,
+but both strace and gdb come with a standard Linux install,

 -- Package manager with signed binaries and easy backup/reinstall.
+There are many Linux packaging systems, including Fedora's rpm-based yum package manager,

 -- Fixing configuration problems with commands instead of GUIs.
 GUIs are good for some applications. They are clumsy and error-prone for fixing configuration problems.
 Many Linux config problems can be fixed by a simple script that can be pasted into a terminal.
