Apple recently announced iOS7 and one of the many features in the OS overhaul is the use of a cards interface and multitasking. To all webOS users past and present, that is not new at all, and is one of the beloved features of webOS. Swiping up an app to close it, and easily switching between running apps in the cards system was simply awesome.
Now that webOS has been put to open source pasture, we see this yet again. Previously Blackberry took a page out of webOS cards and gestures with BB10, and now Apple does the same.
As Steve Jobs said, “Good artists copy, great artists steal”.
