Not only beforehand: you can use the same page for the minutes as well and the "secretary" doesn't become the neck of the bottle. The page should be updated during the meeting and links added to other relevant material as needed.

No, not during the meeting. I think it's rude for people to be using devices in a meeting unless it's necessary - demo'ing, presenting, etc. Not only that, but it will make everyone else in the room uncomfortable, and the person on the device won't be paying attention or contributing much of anything.

I guess my experience has been different: we've found it very effective to have the decisions documented and reviewed before the meeting ends. This is for 3-6 folks on a small team, either face to face or on the phone/skype.
