I have tried lubuntu, mint lxde, opensuse lxde, & they all are very similar but none run as well on my ebox as does wattOS.
I have tried slitaz, puppy, mac pup, e, & bodhi. I guess I just couldn't adjust to their enviroments except for e which didn't runs so well on this box & bodhi which I really like. That is one worth trying out.
