Harvard 2013 (HBS) - Calling All Applicants

I know multiple people who got into HBS last year using a 2-page resume even though they only had 4-5 years exp (obviously those with 10+ years exp, or PhDs with significant research, would be easily justified using a 2-pager). So clearly it isn't an automatic ding. BUT, Dee specifically recommended using a 1-pager, so that is obviously their preference. Also, for most of us, going onto 2 pages will force us to use less and less impressive content as we fill up that second page. I believe it is more about quality than quantity. I want the adcom to read my 1-pager, which is jam-packed with "great" content, and come away impressed. I'm worried that if I used a second page, my "great" content would be diluted by simply "good" content, which is the filler I'm using to populate two full pages. So the adcom's overall impression would be lower, even though I have more content. Also, I don't want to be seen as a resume-stuffer ... any of us who have recruited for our current employers know what that looks like.

Finally, while this is probably personal preference, I strongly believe that if you're going to use 2 pages, you have to use the full 2 pages. I don't think it is considered professionally appropriate/standard to use only 1.25 or 1.5 pages. What are others' thoughts on this?
