Having just returned from South Africa on KLM earlier this week, a few random observations:
1) You can just about eliminate all thoughts of having an open middle seat next to you in economy comfort as they were constantly bringing people up from coach throughout the first couple hours of the flight
2) The handheld control unit for the video sure works a lot better than Delta's touch screen controls.
3) For my money, the KLM Crown Lounge 52 at Schiphol has to be one of the nicest on the globe. Outstanding food (hot and cold, changed throughout the day, choice of two soups), fully stocked wine / champagne bar, Heineken on tap, Apple ipads scattered throughout the club, current newspapers from around the world, showers, deep sleep area (darkened quiet room with lounge chairs -- wake-up calls provided) and probably a few things I've forgotten.
4) When my AMS-ORD flight was cancelled, the Dutch had a rather structured manner of handling rebookings: those of us in the lounge that were on the flight were assigned numbers based on status (business class, then Diamond, Plat, Gold, etc.) and we were called to the desk for re-booking based on our assigned numbers (rather than wait, I just jumped on Delta.com).
5) You know the food on KLM is delicious because all the packaging tells you so!
