When I read stuff like this I often think that people just don't understand what the Beatles did — and the Beatles were more than Lennon & McCartney, but two other band mates and an entire team behind them who were themselves talented. But to get into Beatles territory you have to have spent a few years at the top of your field, and then create a breakthrough product that redefines the field (in their case it was the concept album). So yes this case study of a redesign (really a facelift) looks good, but it hardly redefines the medium.
