ZW has "one app for each task" as a policy.That's a big reason why I've never bothered to really look at ZW. I'm seriously allergic to that approach. Vector's choice of apps -- and the kmenu not being simplified -- are some of the many reasons I find it such a great distro.
Your mention of kmenu gives you away as a KDE user, so I would assume that you're also a VL SOHO user. Great choice!
But there was once a distinction in the VL world that I feel is being forgotten more and more these days.
Once upon a time there were two versions of VL, one big and full-featured with everything someone like you could want, the other lightweight and minimalist for those who want a fast system they can build out as they choose. But as of 5.8, I really feel that the latter is being forgotten, and we've ended up with two of the former, varying only in their default desktops.
I mean, 5.8 Std comes with four different browsers. Even ignoring the question of whether anyone actually wants
four browsers on their system, you have to ask yourself if that even comes near
being light & minimalist.
One of the glories of Linux is the wide choice of distros one can use. There really is something for every taste.
But please, people. Let's not forget that this is really the home of two
distros, for two different tastes.
