After waiting two weeks for my free model M, I finally got it.

I wanted to try the retr0bright, but after a good cleanup it seems to me the keyboard doesn't need that treatment :



Here is the before_cleanup potato pic :

I'm glad that it's working fine with my PS/2 to USB converter (unlike my Cherry which just "die" after a few sentences). Feels great typing on it, but it IS loud !
I think I prefer my white Alps keyboard, but I'm gonna give this one a try for at least a few weeks.
I think the wikipedia entry for this model could be updated, because it states 1991 as approximate date of manufacture, and this one is from 1989 (correct me if I'm wrong, I'm new to this after all).
