Care to explain why "you are out"? The client-side input created using the coordinates of your mouse (or movements on touch screen) generate entropy (randomness) which is couple with a random generator to create a bitcoin wallet. Can you suggest an easier or more secure way to create a wallet? I mean we could just provide you with a wallet but then you'd have to trust us. The client side input makes this a trust-less system that can not be duplicated since input is coming from the client-side. This is the same method bitaddress.org uses. to create secure bitcoin addresses. You can even create wallets completely offline.
