Disappointed with the BS
Come on, "deep" pixels? WTF? I like the idea of local facial recognition capabilities because that has at least not the issue with leaving the biometrics where you can get them (on the shiny case with TouchID) - until someone finds a way to record enough data. I'm betting Hamburg's CCC will be about the first to try, and possibly succeed :).
I hope it's accurate enough that it won't work after US Customs has been working you over to get you to unlock the phone, but in any case Id' switch it off for those occasions and revert back to a password or PIN as that is legally protected. Just in case you make the mistake of crossing the US border with confidential information..
In general it was interesting, although as always I had to wrestle with a profound allergy for their overuse of stock phrases like "amazing", "fantastic" et al, as the nation I hail from shares with UK Northerners a profound distaste for this kind of self-preening. I presume the US needs this, but it sure as hell would create the wrong impression in a boardroom meeting with our company.
Was there anything *new*? Umm, apart from the facial recognition thingie and VR that seems to work well and hopefully precise enough to support medical applications (imagine an MRI projected prior to surgery) not so much, it was all more a progression, like the upcoming 18 core iMac. So, lots of evolution, not so much revolution.
BTW, I don't WANT phones to have better and louder speakers - there are already enough idiots playing songs on handsfree and ignoring years of sound engineering by holding the phone at a 45º angle and talking into its edge whilst on handsfree. Killing that off via angle detection and a mandatory 2 hour video lesson on the progress made in dual mic echo and environment cancellation techniques before it could be used again would have been more beneficial, but that's just me before coffee.
