I'm trying wattOS LXDE, I'm not an expert user, but I think that wattOS is more reactive than lubuntu 13.10.
I like to have an OS that is clean, and minimal, so I can install only the software that I use.
The only "problem" that I notice is the look, that is not so smooth as in lubuntu. This depends on the basic settings or there are some softwares missing for keep the distro light ?
the lxde wattos doesnt include propriety drivers for the monitor if that is what you are referring too...
there is a way around that to bring the graphics look into touch
