Wow, Enlightenment is very impressive and seems to be a good UI for PDAs. Once it matures quite a bit (i.e., not make it nearly impossible to add menu items, a working file browser, not having to rely on the "remote" program to change things not implemented in menus, etc.), I'd consider using it over Xfce. The animation is pretty and all, but it could benefit from a custom theme that isn't so cpu-intensive (while preserving as much eye-candy as possible, as it's part of the appeal). Overall, a thumbs-sideways; it will be a thumbs-up once it becomes more mature and user-friendly.
