While in a waiting room, at a friend's house, or even in the grocery store, there are times you can't rip out the page or take the magazine with you. I have found that my cell phone will take perfect pictures of the ingredients and the instructions. You can always blow up the photo on your phone, or send them to your home PC.
Another plus: you have the full recipe available while you are at the supermarket and can use it as your shopping list. No forgotten components when you go to prepare the dish.

I do the same thing with my iPod, especially at the library. I can take a picture of a recipe or health tip, etc. Very handy!
