False. One can lift their ski up and grab the tail of the skin and rip it off in a relatively motion (takes practice to do it smoothly). If I am in a hurry or psyched to ski a line I can do this and stick the skins in my jacket (recommended anyways to keep them sticky). Whole transition takes less than a minute.
With Dukes, the fastest I have seen anybody transition is 2-3 minutes, and even that's a quick person with no problems on the ski/skin lever.

As for bindings, here are my own experience-based opinions:
-BD Fritschi: Cheap, full of plastic, and generally weak. They prereleased like crazy whenever I used them. Avoid like the plague.
-Marker Dukes: Overall felt stable, didn't have much of a problem with them on the downhill portion. Transitions were a huge pain in the ass (see above paragraph), and the high plastic content definitely lent itself to a lack of stability on the binding. Not worth the price.
-MFD: I have these and the FKS140s on Caylors. I LOVE them on the downhill portion of things. Very stable and feels very normal on turns and such. One can reliably use these for lift serve as much as any alpine binding, which makes it ideal for shorter backcountry trips and sidecountry stuff. Huge downside here is the weight. This is a well known fact by now. I don't mind how burly it is really, but I can see how it can be a drag to others. I would not take this system on a longer tour.
-Dynafit Radical/Vertical: These are, by far, the best option for a dedicated touring setup. The beating of lift serve is not ideal for these, but purely in a weight, simplicity, and retention standpoint these are king. The downsides are that you need a compatible boot (more $$$ if you don't have one already) and, again, they won't work for in bounds stuff very well. Definitely not a choice for an everyday setup. The bummer is that the Radical has a superior toe piece, while the Vertical has the superior heel, so you have to pick which half you like best unless you want to buy both and make a frankenDynafit (so...much...$$$). I know somebody who has done this (he is sponsored by Dynafit, though).
The new stuff coming out (Adrenalin and Tracker/Guardian) seem like improved versions of the Duke. I have no experience with them so I cannot offer advice.
Hope that helps.
