revengexx is right. It's just a mock-up rebuild for web or app presentations. At the moment there are no good mock-ups in the wild. Only bad modified press-release fotos. That's why I build it. So not my design.
It's a recreation of the Touch Cover coming from Microsoft, so that's how it's going to be. I think it's ingenious, it has some separation of keys, with a real physical feel, but it remains light and doesn't scratch the screen. There's also a Type Cover, which will have click-keys if that's what you really want.
