There are other options. You could use another OS where installation is easier,
but you would have a file system that can be compromised easily unless you are
willing to devote most of your waking hours trying to keep out intruders.
It is a trade off. With Linux you get a system that is modular and powerful. We
use scripts, daemons and modules in place of a centralized registry that can
become damaged and gets fragmented. Most users don't need all of the features
and power users will find ways to do take advantage of them. Most do not fear
the commandline after awhile. So don't think of it as being hard, but as having
power at your fingertips.
In addition with Linux you get choice which means that Linux has lots of
variety. This makes it more difficult for vendors such as Sun (VirtualBox) to
tailor their products. Maybe someday there will be more standardization, but
don't count on it. Linux users are an odd lot. They like choice and dislike
being told that there is only one way. It is the quickest way to get a reaction
from Linux users. Just try to limit their choices and you will find out. They
don't want there to be one kind of Linux or one way to do anything. They want
both the GUI and the commandline. They to be able to choose the distro that
suits them best. They want it all.
