KDE on CD-ROM
The official KDE packages will always be available to download for free from the KDE FTP site. However, if your bandwidth is limited or you just like a permanent copy, there are ways to get KDE on CD-ROM.
Service: Various Linux Distributions|
This is a typical way of receiving KDE on CD-ROM. The advantage of
using the version that comes with your distribution is that you are
fairly certain that it will be setup to handle your distribution's
particular directory structure, etc. The disadvantage is that you
will likely have to wait a few months for your distribution to catch
up with the latest version of KDE.
Some distributions contribute back to the KDE Project in many small as well as very large ways. This includes paid developers, hardware, misc expenses, and more.
