I'm not sure about just reading a six page memo out loud to everyone. That seems like a great thing to email to everyone. Some of my least favorite memories from college are the couple of classes I went to where the professor basically read the book to us. The difference is, I'm guessing, that attendance isn't optional at an Amazon meeting.
Personally I like keeping presentations on the short side - only using slide shows for ancillary data like citations (which I find awkward to fold into the flow of a speach) and graphical data. Unless something is really interesting or very important, it's only going to get 5-10 minutes of people's attention.
For clarification, the 6 page memo is not read aloud. Each person is provided a copy at the beginning of the meeting and the first 10-15 minutes of the meeting are completely silent.
This actually works pretty well because in the real world people usually only skim the info provided in advance of most meetings because they only need to "get the gist" of what's being said. This forces everyone to have a thorough understanding and promotes more thoughtful discussion.
You don't read it out loud. You bring printed copies (or send electronically) and everyone reads it for themselves, in silence, at the beginning of the meeting.
