Watch how this guy modified the skins of Windows CE to make it look and function nearly identical to the iPhone’s interface. Watch until the very end, where he even has the “flicking” through songs down to a tee.
Within the next little while, as we have seen in the past, individuals and companies will start immitating Apple’s great interface. Microsoft did it with OS X, numerous mp3 player manufacturers did it with the iPod, and it will happen again with the iPhone. Competition is always a good thing, however, as it drives prices down. We know that Apple will always release the highest quality product.
