@anthropy My mom hated how Windows programs kept "switching the buttons around." So I switched her to Linux. That was 20 years ago. She loved Linux. Her computer just worked. My dad and my sister wanted to switch her to Windows so many times and she wouldn't have it.
She used Linux for nearly 20 years and was happy with it. We started with Linspire, then went to Suse, then Vector, Fedora, and finally Ubuntu, and it always just worked.
