I've recently downloaded Cook's Illustrated for the iPad and I'm thrilled. The first thing you notice (aside from Kimball's continued rambling about the virtues of rural Vermont) is that the photos that accompany the articles beautifully morph from black and white to color. Then you can click on the products in the comparison, but best of all there are imbedded demos for each recipe, not clips from Americas Test kitchen, but a more concise run through of the recipe with visuals of the harder to explain motions.
It isn't cheap, but it has all the content of the magazine, plus the extras I mentioned, and it stores more easily. If they had back issues, I would buy the whole lot.
Today I caught that fish again, that lovely silver prince of fishes,
And once again he offered me, if I would only set him free—
Any one of a number of wonderful wishes... He was delicious! - Shel Silverstein
