My fixation on KMail is simple, that I want to have an email client which is truly integrated in my DE and uses mostly the same libs. (Running Evolution btw.).
If I just run KDE as an application starter, I honestly rather use Xfce or even more minimal.
The whole selling point of an DE (for me) is that things are integrated.
I run my VMs with QEmu or VMware.
