Multi-photo vs. Single photo on a layout

I love the look of the single-photo layouts I have seen, but as a traditional scrapbooker, I almost never did them because it seemed like a HUGE time commitment with not as much payoff as a layout with multiple photos. However, once I started digi-scrapping, I find that I do a lot more layouts with only one photo because the time it takes to create a layout is a lot less and with digi, if I really like a layout I create, I can copy it and use it later for another photo.

The time thing is the biggest thing though. I am MUCH more likely to do that kind of layout now that I know how quick and easy it is. I can even create one or more layouts with photos in mind (or not!) and add the photos later. I know I could have done this traditionally too, but who has the time!?!
