I, too, am quite a fan of trackpoints on thinkpads. I used to be weary of them but compared to a trackpad it's just so much easier to use, takes less strain too.

Of the choices, I prefer normal mice. I have a nice MS Optical, in the style of the original white one, but black; it matches my thinkpad perfectly. It's also very nicely weighted, unlike my other new-style MS Optical mice which are much too light.
