One page website with Drupal 7 I saw many personal or company websites with one-page website style. the one-page design is very good for giving as quick as possible all information that you have without letting users click around to find out who are you and I really want to apply them in Drupal.
I also tried to implement one-page website by using the single page website module (http://drupal.org/project/single_page_website) and it's quite nice for the simple pages.
So my questions are:


Which is the best way for making one-page design: create one-page templates or using contributed modules?
The advantages and disadvantages for Drupal to make one-page design? 


I haven't done any one-page design before so can someone give me the right direction for that.
