Disclaimer
I am not an expert, please do not ask difficult questions :-)
I have given up compiling KDE from sources since 3.x, so I have no idea about KDE4 compilation, just use J. Riddell's debs
Some info here is probably incorrect or plain wrong, Caveat Emptor!
I am a long time KDE (1.x-) user and fan
Icons and images are of the respective organizations. I have attributed wherever possible
Agenda
KDE in Two Slides
What's new in KDE4?
Hands on Demo KDE4 Alpha aka very few things work ;-)
Why I think KDE is cool (& useful)
What is KDE
Desktop Env like GNOME, CDE, Xfce, runs on top of X11
Written in C++ (no Mono or .Net stuff)
Uses Qt from TrollTech, Norway
65 languages
GPL licensed
Linus' favourite desktop :-)
Mark Shuttleworth use KDE on his desktop (http://www.phoronix.com/scan.php?page=article&item=732&num=5)
What is KDE
v3.5.7 latest stable (22/May/2007)
v4.0 in development offers completely new & exciting features
Usability: Officially, KDE3 meets ISO9241 (http://dot.kde.org/1179818755)
My guess: More contributors from Europe, S.America
KDE Structure for Dummies
OS, infra (dbus, hal) and libs (libpng, zlib,pcre, xine-lib etc)KDE CORE
KDE MultimediaKDE LIBS
KDE PIMWebImage and Video
NON CORE KDE APPS, Non KDE Appswww.kde-apps.org
KDE extra-gear
KDE4 -Many new things
strigi fast search
Phonon Audio Framework
Solid Hardware support
visually appealing GUI
kross scripting
KDE4
Will run (as expected) on many unixes, Linux, BSDs, and gasp... Windows and OSX too.
KDE4-Alpha released: 11/May/07
Final release in Oct-2007
Build system uses cmake. Code hosted on svn
QT available on Win & Mac -GPL
Completely new architecture
KDE4
Phonon: MM API supports gstreamer, NMM, Helix, Xine, DirectX-Windows backends
Better Accessibility, HIG conformance
SVG rendering everywhere
No more app names beginning with k -Big Relief :-)
App cleanups and merging
KDE3 compat libs to support old (kde3) apps (2011)
Sample Oxygen Icons

KDE4 Phonon
Phonon is a new KDE technology that offers a consistent API to use audio or video within multimedia applications. The API is designed to be Qt-like, and as such, it offers KDE developers a familiar style of functionality
Not a xine engine replacement
Handles volume changes etc (eg: loud music+incoming voip call)

KDE4 Solid
After a lot of hacking behind the scenes, a new initiative to improve KDE's interaction with network and hardware devices has been launched. Solid will provide a robust basis for the dynamic modern desktop in KDE, which needs to be aware of available hardware and networks, paving the way for innovative functionality.
Users should see KDE applications taking advantage of Solid in KDE 4, from the most basic Plasma applets and complex applications to desktop-wide awareness. Developers will be able to take advantage of a robust, flexible and portable API and will be integrated into the Plasma engine. It will make use of existing technologies like HAL. Solid will also include a knowledge base providing a way for users to easily provide feedback on incorrect behaviour.

Experiencing KDE4
Use opensuse LiveCD with KDE4 (http://home.kde.org/~binner/kde-four-live/)
Install KDE4 packages on kubuntu feisty fawn (http://kubuntu.org/announcements/kde4-alpha1.php)
Compile from source (http://techbase.kde.org/Getting_Started/Build/KDE4)
Far Out in the Future...
One of the first implementations of Semantic Desktop : Nepomuk KDE

See van den oever's presentation slides
Cool KDE Stuff: konq
uber app: web browser + file manager + many things
Save/email pages as PDF
Tools->Archive Webpage: Create a single tarball with all images, html etc
Tools->Speak Text
gg: and ggx: - Google search

cpan: lwp
browse bluetooth
locate: linux or bug: 110385 or dbug: 68635
Cool KDE Stuff: GHNS
Get new wallpapers, themes, right from your desktop (see demo)
Cool KDE Stuff: strigi
strigi Desktop search Standard part of KDE4 see now on KDE3 (kubuntu feisty fawn)
apt-get install strigi-daemon strigi-applet strigi-plugins

Some Myths
Biggest Baddest: GNOME and KDE don't get along well :
Nothing can be more wrong than this: eg Guademy 2007 (GUADEC + KDE Akademy)
Work done at FD.o
Common standards: dbus, scripting interfaces, HIG etc
Many common underlying libs (okular uses poppler, xine-engine support in kde etc)
There are major differences of opinions though
