I don't know about that. I've gotten several to at least consider it by waving the "virus-free" flag in front of their panic-stricken faces.Old people won't switch to Linux
I can proudly say that my family has been completely Microsoft-free for nearly a year. Mine and my sister's laptops both run Xubuntu 11.10, my dad's desktop runs a custom Debian Squeeze base, and my girlfriend's boots Mint LXDE 12. I first used KNOPPIX to backup data from a dying Windows partition, then used it to bypass Windows XP's fidgety wireless drivers to access facebook. It took a brand-new Vista install getting a virus to push me over the edge and replace it with Ubuntu 10.04. After realizing that everything I could do in Windows I could do in Linux, but better, I fell in love and never looked back.
