Résumé:	Article consacré à la ruée des consommateurs sur les tablettes tactiles, qui seront vendues entre 50 et 80 millions d'exemplaires à travers le monde en 2011, et offrent de nouvelles perspectives pour les producteurs de contenus et les prestataires en numérisation. Les tablettes sont plébiscitées par des secteurs professionnels de plus en plus nombreux et inattendus. Le marché des liseuses électroniques recule sous l'effet de l'avancée des tablettes. Le développement des contenus en ligne est freiné par la position monopolistique d'Apple, critiquée par de nombreux éditeurs de contenus. Témoignage sur le changement d'habitude de consommatio par un utilisateur de liseuse électronique.
