Using scroll-driven websites on a Mac with its gesture-based trackpad scrolling is often a beautiful experience, and it's usually also delightful on an iPad. Sometimes it even translates well to mice with scrollwheels. Using the same site on a windows laptop with weak trackpad gestures, where you instead rely on arrow keys, or awkward middle-button-synthesis for scroll, it's all too often completely frustrating. Even this piece seems to regard users using anything other than an apple trackpad or a scrollwheel mouse as a secondary concern.
