You can’t lose what you never had, though. ;-)

Looks like the Gnome Disk Usage Analyzer but for KDE.

I don’t hate Windows but I hate being forced use it. I feel that I’m very effective when using Linux and just don’t like when I am being slowed down. I want to use my machines to get things done and don’t like it when operating systems and tools get in my way instead of enabling me to do what I need to do. Hating Windows is pointless because it’s a waste of energy: it is what it is, why expect more?

I recommend that you transition instead of switching. That way you have a way to roll back If the distro you are trying out proves not to be what you expected.
