Wrt to the iPad: When I had a small notebook computer, I still didn't enjoy using it in the kitchen -- not only the risk from spills and gunky fingers, but I find it easier to read from printed paper, and infinitely easier to make notes. But I gather there are all kinds of stands and covers for the kitchen iPad, so that may not apply. It's a pretty expensive solution, though.
My general method is this: recipes that aren't in my cookbooks or in the shoebox files inherited from my mother are all on my computer, in one directory. I back them up regularly onto a thumb drive (which keeps me from worrying about losing them all at once). When I try a new one out, I print it out. As I cook, and even more afterwards, I make notes and revisions. Then [in the ideal world] I enter the revised recipe on the computer, and save it to a 'made' directory. If it's one that I plan to make again, I print out the revised version and add it to a three-ring binder (where the recipes are in plastic page protectors).
I don't often clip from magazines or papers or catalogs. When I do, I apply the same method: if it's a keeper, I enter the revised/annotated version in my recipe directory, and print out a copy for the binder.
I'm always behind on entering the revised, tried-out recipes. But -- and this is the key -- I keep those all in a kitchen notebook, taped to the pages, and I made a 'table of contents' in the front of the notebook so that I can go back to them easily. Once I find myself going back for the second or third time to the same scribbly page, that's my signal to sit down and get it entered so I can put a copy in the more durable binder. The notebook also makes it easier to enter a batch of tried-out recipes, as they're all in one place.
So one place to start, with a lot less overhead than a new machine, would be to try taping your pieces of paper into one notebook. That way they're easy to flip through and easy to make notes about. If you number the pages, you can make a rough 'table of contents' that will help you find one more quickly. And you can keep adding them to the notebook as you find them stuck in between cookbook pages, in drawers, etc. (I've been there!)
That might be enough organization to get over the hurdle of "where IS that recipe?" It also makes it easy to add them to EYB as personal recipes (maybe even including their page numbers in your taped-in notebook).
