The fear of failure factor is one reason why potential newcomers to the Linux operating system never complete the switch. After all, when was the last time you saw a sign in a big-box computer store identifying the aisle labeled "Linux Loaded?" Most desktops and laptops come out of the box with Microsoft Windows preinstalled. Don't even think about asking about Linux in an Apple goodies store. Linux options in most storefronts are limited at best. Buying Linux-loaded computers online can be a safe but often pricey option.
