So Ipad has magnets in it.. would be great for sticking pictures and notes to the refrigerator. I'm imagining a fridge, ipad stuck to it holding grocery list (champagne, caviar, veal) with a nice pair of $900 designer shoes sitting next to it... AWESOMEI think it's just the "smart cover" that has the magnets-- in fact, they are the way that the cover tells the iPad that it's on or off. (Remember the ImageWriter cover interlock? ;-)
Or a lot of laptops. The strongest magnets I've come across have been in hard drives. But they are arranged in pairs, and don't have much pull outside oftheir dedicated area. I haven't really given it much thought, but in the old days of weak magnets, you might end up with a large surface in order to get enough magnetic strength, which would have more fallout for unintended purposes. Magnets now can be so strong, they can be physically tiny, which may limit the affect on things that they aren't intended to
