> It's quite nice that the ipad mini does not have whatsapp or SMS plugged into it, so I can use it exclusively for reading books or playing music.

Both a phone and a tablet can come with WhatsApp, it's a user choice whether they are there and the frequency of checking them. Global muting the apps is also an option.

I understand your point, but it is a point mitigated by user intervention. Now, if we want to say reading on a bigger screen than a phone is a better user experience, I'm on board with that.
