Equinox Desktop Environment (shortly EDE) is small desktop environment, built to be simple, to have familiar look and feel and to be reasonably fast. Various UNIX-like operating systems is place where you can run it.
It is based on modified FLTK library, called eFLTK
Pros:
* Very fast and small (both in ram and on disk)
* Reasonably similar to Windows, but configurable
* A whole desktop environment, based on FLTK, a number of apps available
Cons:
* Many important features and apps missing - still "under construction"
* The toolkit development has problems with API stability and compatibility
These are only meant to be rough guides. I do not think that they are accurate in Memory usage but show a rough comparisson. I tried idesk vs rox-pinboard on another leightweight system and Rox won out (instead of idesk this time).
