Gnome 3 in Debian not for you? Try KDE in Debian Wheezy!
To install KDE desktop in Debian Wheezy, install this meta-package:
$ sudo apt-get install kde-standard
This will pull in needed KDE packages for a desktop.
If switching from gnome, during the process you will be asked what login manager to use: gdm or kdm. If going to KDE, select KDM.
When all finished, reboot and you will come to a nice shiny KDE login screen. Here before logging in, click on the gear wheel and choose KDE Plasma Workspace.
I also suggest installing the KDE package manager on Debian, apper.
$ sudo apt-get install apper
KDE Rocks! How do I remove gnome?
To totally remove gnome, the command is:
$ sudo apt-get remove gnome*
Once this complete, run:
$ sudo apt-get autoremove
