So nine possible use cases for your smartphone photos, of which only the last two present any kind of problem. And, notably, in three of the use cases the EDoF-equipped phone will produce better results than an auto-focus equipped device.
All of which belies the roasting that Nokia's new devices have been getting in online reviews, again emphasising that the very people who write the reviews are the geeks, the power users, the top few percent of phone users in terms of technical awareness, who love snapping macro photos (of phones, accessories, meals, signs and so on). Nokia are betting that most (normal) people will fit into the first 6 or 7 use cases above and therefore will get as good, or maybe better results with EDoF than auto-focus. Certainly real beginners will shoot better photos, since there's less to understand and therefore less to mess up.
