I'm not sure whether I should say this in this thread or not...but...
I've always been a Gnome user but I've also been using XFCE.
I had tried SUSE KDE3.5/4
, Kubuntu KDE3.5/4
, Mint KDE4
, PCLOS KDE3.5
(Mandriva is pending). And NONE of them suited my personality and likes. All of them seem to have tools and applications I dislike. I had never liked any KDE distro before I tried VL SOHO. Its got the best apps, best tools that are easy to locate and are great to use. Some of the reasons could be also because of the old(er), easier to use and friendly-er KDE3.5 DE. The other minor reason is that most distros such as Mandriva and SUSE do not have as great support for my local language layout (Thai), so keep it up!
I've never been impressed with the KDE4 Menu. If you're migrating VL SOHO to K4, it would be a lot better to have the old menu as follows...
The other reason is that KDE4 features and control centre are somewhat more Advanced and options are harder to locate and tools are less userfriendly than the ones on KDE3.5.
I've never see the use of the new K4 desktop with those plasmoid widgets and the shaded, bordered area where all the icons are located. It just feels uncomfortable and bloated (uh, just like Vista, perhaps?) at the same time they're very eyesore and looks very ugly. It would also be great to have the old icons arrangements and the old desktop just like the picture above.
So in conclusion, I would suggest you stick with K3.5 or if you're migrating to K4, make sure you do some alterations with the desktop to look and feel as similar to K3.5 and the current VL SOHO version as possible. K4 could ruin the userfriendlyness of VL SOHO.
Yes, the picture above is a screenshot of Mandriva One 2009.1 Spring.
No, I'm not saying Mandriva is better but I'm implying that its got some very useful features and desktop alterations.
I've never even used/tried Mandriva KDE before!
