The original social medium (letter writing) has been smashed together with modern technology (mobile devices) to yield the book The John Lennon Letters in app form. The book/app is a collection of letters and notes written by John Lennon between 1951 and 1980.

Jarvis Cocker, who you might remember from the British band Pulp, has written a rather scathing and very Cocker-like review of the book  which you can read here if you can stomach his tone.  God help us if he ever gets his hands on the app and reviews that!
