I'm getting more and more the felling that Kubuntu is lagging behind all other KDE4 distros. Few things that are *keeping* me at Kubuntu are apt, good repos and this site.
I took a look at other KDE4 distros like OpenSuSE and Fedora, and they both have some things that are special to their distro.
OpenSuSE ports parts of KDE4.2 to 4.1 for usability reasons, so you can choose between normal and plasma desktop, and let us not forget that Kickoff menu is a SuSE menu.
And Fedora has a "security centre" where you can manage your firewall and other stuff nicely through GUI...
Ok Kubuntu has a nice installer which is quite new-user friendly but Adept still needs a lot of works in its "super" mode, the add/remove mode is really good but the Adept itself is years behind Synaptic.
While SuSE is on "bleeding edge" and back porting future options and Fedora is stressing the security factor; Kubuntu should take for its priority usability and user friendliness.
KDE4 at this point lacks a very important tool: "auto starter" which would prompt a window when a data CD / USB key(pendrive) or audio CD is mounted.
This window should prompt:
Open folder
Play music
View pictures
Rip CD
...
And there are other things which can be improved.
The example that I gave is implementable to KDE4 for all distros.
You could ask what we get from that. Well the same thing that OpenSuSE gets from Kickoff beeing a default menu.
Everyone knows that Kickoff is from SuSE and it gives you the view that this distro is really the pinnacle in KDE as KDE takes their "app" and use it.
I don't say that Kubuntu should share every KDE improvement that it develops, only that it should also give of some improvements to KDE community so it can profile as an "big player" in KDE world.
But more than that Kubuntu should have more reasons why a user should use it not just the simplicity of use...
(Kubuntu is just more or less vanilla KDE with apt repo...)
Any comment is welcome!
