John Kirk writing at Techpinions: http://techpinions.com/whither-apple-or-wither-apple/31198 I disagree. I think "mainstream" users don't know what they want until someone gives it to them. I mean how many people were asking for Touch ID? But I'll bet now most 5S users wouldn't want to use an iPhone without it and can't wait for it to come to iPad (and even Macs). Also I'm not sure how you can call things like actionable notifications "power features". I don't consider myself a power user, but I can't tell you how annoying it is to get a text message and have to leave the app I'm in and go to the messages app to respond to it. IMO we should have had actionable notifications long before iOS 8. Honestly I can't think of one feature announced at WWDC that I would consider only for tech geeks or power users. I think mainstream users will start using the features of iOS 8 and wonder why it took so long to get them. My iPhone and iPad would be pretty worthless to me if not for 3rd party developers so I'm glad Apple is showing them some love.
