Ediff is really nice, but it's a bit cumbersome.
I mean if I only want to see the diff and apply what I want how do I use
ediff?
ediff is very interactive and it makes a lot of color noise, moreover it
opens another small frame which on 
"GNU Emacs 23.2.1 (x86_64-apple-darwin10.3.0, NS apple-appkit-1038.29) of
2010-05-09 on linc"
I think is a bit buggy, since if I press "q" it doesn't disappear but I
have to close it manually.

As I discussed with a collegue, one of the problem of emacs are the
non-inviting defaults.

Since no long ago the transient-mark-mode was not enabled by default
(just an example).
I understand that it must be compatible from Dos to Solaris, but many
people try it, see that the defaults suck (from a normal user
perspective) and they abandon, which is a pity (or "natural selection" maybe).

But that's another topic...
