No, it would just be your own lack of understanding of standard terminology, including the classification of systems known as "home desktops" and configurations called "preinstalled". You're of course not the first one to have difficulty understand the Linux gobbledy gook, which is exactly why Dell is insulating his home users from the trauma of having to deal with it.
It's not like Dell didn't try a Linux desktop, Dell added. The Austin, Texas-based company "tried that with Red Hat on the OptiPlex and Dimension lines, but we had too many people not buying and saying we picked the wrong one." By 2001, Dell was no longer offering a Linux desktop to its usual retail customers.
