As a self-published Author my books are distributed through the Sony eReader Store, among other retailers such as as the Apple iBook Store and ITunes.

Sony have struck gold with this concept.
Given how frequently our moods can change, tapping into your emotional state before you purchase an eBook is a stroke of genius.
