I came across this link on a message board and all I can say is Wow! These digital layouts are phenomenal.
Go to http://gallerystandouts.com/ to see some amazing work by very talented scrapbookers.
I've done a few completely digital layouts. Personally I prefer a hybrid or digi fusion approach. I do some of my layout on the computer - collages of photos and/or titles and journaling printed on my background paper. Then I usually put it all together with tangible embellishments. I like the actual feel of the layers on a page and enjoy the process of paper crafting.
Stampin' Up! is debuting new digital scrapbooking software and downloadable elements next month. Since I already have software for creating digital pages, I won't be purchasing the software but I know I'll be taking a look at their images to see what I want to incorporate into my scrapbooks.
