While it retains all of Linux's power and flexibility, the user doesn't need to change much of the desktop layout to become productive. LookingGlass is a set of configuration scripts for the fvwm window manager. It's pretty and very, very practical. Once again the user must fiddle under the hood of the formula racer. This is still beyond the normal user, despite the beautiful interface Caldera's OpenLinux provides.
Caldera is still way ahead of the competition in terms of packaging, in general.
A perky geek with a bow tie and pocket protector would have to holographically pop out of the computer to talk you through the simplest tasks. But even to install Linux at this point in time, users must now know how to repartition their disks, create swap space, create and check filesystems, compile kernels and install kernel modules. The holographic geek would have to take over all of these tasks on his own. I'm not even sure Linux is for mainstream programmers, anymore. It used to be that programmers had to build their own interfaces, create their own libraries, and pretty much build things from the ground up.
