Thanks, Christopher. Just in response to your points:

1. Agree, completely, but ‘traditional’ operating systems can be unpredictable and noisy, no matter how much you try and shut yourself away in one app.
2. No, it really isn’t. I enjoy typing on both.
3. Not for a sustained period, personally (although some people might). It’s the ability to pack the device away and not worry about losing significant battery while on stand-by that makes a huge difference, though. It’s all about convenience for me, and the less I have to charge a device, the more convenient it is.
4. I don’t agree with this, I’m afraid; you can place the iPad with Magic Keyboard comfortably on your lap, too.
