Swiss knives have pros & cons, and worshippers & haters. I'm just a user, and I am pleased by those features I use (catalogue, keywords, pic processing). It is indeed slow
- at import : I don't care, doign just a few pics a time
- at display : bad. I often shoot 2-3 times per pic (precaution for MF imprecisions and camera shake, using low speeds most of the time). In that case, being able to quickly eliminate the worst ones requires quick switching. Too bad. So indeed, for culling, an alternative like PM sounds good.
