I used to think this too, but then one day a senior recruiter pulled me aside and said you have a great resume, but it tells too little about you to really know anything and managers are assuming you have not done very much. So I rewrote it to fill 3 pages with all the stuff I have done (I am an engineer) and now I get more calls. The only time I have seen the "get them in 3 seconds" approach work is at job fairs. You want a 1 pager for those. It's more like a business card than a resume. Remember, a resume is the place to make yourself sound the best you can and you do not want to cut that opportunity short. 2-3 pages is about right for a mid-career professional. I have seen advanced academic resumes (vitas) run 10 pages.
