Time to go back to using Debian on my laptops as well. For many years I have been using Kubuntu on laptops and Debian on desktops and servers. It always was a bit uncomfortable, but it makes you more aware of differences between distros and package versions so it is even useful.
Now I have an excuse to go 100% Debian again. Hooray!
I wish best of luck to Kubuntu as a community distro and the above is just a reflection of my personal preferences. I do think that I trust Debian more with community support though.
