I must admit that I returned to IDO after a while since my usage of
icicles was insufficient for me to remember how to use it. It just
seemed a tad too comprehensive and complicated - I got confused too many
times with the plethora of options. I can see how someone living in
Emacs would love it, but at the time it frightened me off. Possibly now
is the time to return to it.

As it is my completion/ido set up works well for me and is as simple as:

| (setq completion-ignore-case t)
| (require 'ido)
| (ido-mode 1)
| (ido-everywhere 1)
| (setf ido-confirm-unique-completion t)
| (setf ido-enable-flex-matching t)
| (ido-mode 'buffer)
| (ffap-bindings)

 important and urgent problems of the technology of today are no longer the 
satisfactions of the primary needs or of archetypal wishes, but the reparation 
of the evils and damages by the technology of yesterday.  ~Dennis Gabor,
