Not to mention that although the Pictos cloud glyph and the iCloud version share the same 4-cloud structure with similar shape proportions, they are definitely not the same icon. The Apple version's 2nd cloud on the left (the small one) has a decidedly flatter curve to it than the same cloud in Pictos which sticks out further. If you overlay these two icons (which should have been the first thing the author did in his entry, but chose not to) this difference and other very small differences would have been made obvious. Having the same general shape and layout is one thing but being exactly, pixel-precise the same is quite another.
