Bodhi is a minimalistic, enlightened, Linux desktop.
We know there are hundreds of Linux distros that already exist. So then the question becomes, why are we making Bodhi/is it redundant? Bodhi is largely set apart from other Linux distros due to the fact that it utilizes the Enlightenment desktop. If you look at all Linux distros as a whole you will find fewer than a dozen active Linux distros that use Enlightenment as their desktop.
Why use Bodhi over other 'light weight' distros? Simple, using Enlightenment instead of other light-weight desktops such as LXDE or XFCE (if you can even call XFCE light anymore) is that Enlightenment is pleasing to look at in addition to being fast on all sorts of hardware.
