This is the first time I am writing, but I have been a Linux user for quite a while. I used many distros, but always returned to Ubuntu. I have used Kubuntu, Lubuntu and Xubuntu too. I had a mixed feelings about Ubuntu with Unity. I tried to get used to it from 3 releases, but I don't think I could. I installed gnome 3 in quantal. It was a good experience. I hope the Ubuntu users wouldn't flame me, but I found gnome 3 useful. I thought of using Kubuntu for a while and I find it responses just like Lubuntu. I thought of installing gnome3 in Kubuntu, but when I saw the amount of files to download, I dropped the idea.
Both Nautilus and Dolphin has dual panels, but Dolphin gives a better information, when you hover over the icon. One can even see what's inside the file or a document. Rekong seems to be nice, but I am a Firefox user.
I don't need to install Compiz to have effects. They are default. All kinds of applets are available. If you need more, you could download and install in one click. Themes, wallpapers are galore and they are available in the same window for download. I have a feeling that KDE had done a better job integrating applications, themes, icons, fonts and so on, better than Gnome, Xfce and Lxde.
Amorak finds out what plugins I need and installs them. Unity, gnome and others have a problem with their default applications. Applications Installation in Muon package manager is a bliss.
What are your experiences?
