In all fairness to WattOS and the developer, it does say in the release announcement...
The result is a light, clean, fast desktop in both cases that can be used to bring old computers back to life or as a basis to start with a clean simple desktop for whatever use you decide to customize into.
I think the minimalistic approach that the developer has taken is great...allowing the user to add what they want instead of forcing the user to take what comes preinstalled. User's tastes vary. For example, I personally dislike GIMP...and don't want it on my system.
So, I will go through the effort to uninstall it and install Kolourpaint.
Having an OS that you can put what you want on, is perfect for me and others. My personal favorite screenshot tool is the Xfce Screenshooter. I added it to WattOS (without the extras that it would install) in less than a minute...
sudo apt-get --no-install-recommends install xfce4-screenshooter
So, as tastes vary, my hat is off to WattOS for the minimalistic approach and not bloating the OS.
