I love User Guides/Reference Manuals (perhaps i am showing my age here). They are a must with every product however "user friendly" its designers may think it is. Anybody who has dealt with teaching "How to use a Smartphone/Tablet" to the elderly understands the frustration of not having a proper guide to give them to read slowly and absorb. The so-called "obvious user-friendly UI" is anything but. There are so many random gestures dependent on context that even i (a tech-knowledgeable person) find them hard to remember and use correctly as needed. Given that a smartphone is now indispensable for everyday work, it is almost criminal to not provide a user guide to the elderly who most need it.
