The word copying is pejorative, so let’s just call it following. Of course Android followed the iPhone’s lead. But what else was Google to do? It took genius to conceive and create the original iPhone. But once it was revealed — and especially once it hit the market — anyone with a lick of sense could see that this was how all such devices should work. If Google had stuck to its original design for Android, it wouldn’t have succeeded in a post-iPhone world — it would have been Windows Mobile without the existing market share.

The first successful implementation of a radical idea is usually and correctly lauded as the innovator. The second is derided as an imitator. But by the time you get to the third and fourth, the idea becomes a category.
