Really nice system. Fast, lightweight despite of using Plasma 5.
Under Debian, network manager does not work on my Lenovo G70 but here it's ok, no problems, finally. Looks fantastically, it's a beautiful Plasma even better than under Manjaro and Suse.
Its weakness is Calamares installer which requires from a user manual allocating /boot/efi partition to install it next to Windows. I cannot understand why this installer cannot do this automatically.
Generally it works fine, I have not faced any serious problem, only some small problems here and there but it is nothing.
The system is usable in the current shape and I hope it will not be worse.
It is worth to try.
