I've been a KDE 3.5.x user for a long time, and while I have compiled individual KDE4.x applications for use on my VL boxes before now, I had not experienced the desktop until today when I bought and installed VL6.0 Deluxe.
I very much like the desktop as I am adapting to it. However, it *is* markedly slower than KDE 3.5.9 on my laptop (AMD Sempron 3300+) as far as navigation goes. That said, a number of things (like OpenOffice 3.0) seem to be more responsive than in VL 5.9. I also like the automounting ( I didn't have to specify HAL or VL-hot ).
On the downside, I have not yet discovered how to have a separate image on each desktop. And I miss right-clicking on a folder and having the copy-to option displayed. Also, Okular seems to be without pdf support (but I will gripe about that in the appropriate thread).
Thanks to all who made this release possible. I've had to do next to no configuration to have a stable working environment.
