The worst thing I'm seeing in the mobile race is the two winners (iPhone and Android) are not adopting any of the good innovative things from the "losers". For example, WebOS is all but dead, had a ton of innovative things like Cards, Just Type, inductive charging, notifications on the bottom, and as far as I can tell, none of those things are being used (or are being used in a much more muted way) but iPhone and Android.
Instead the two big players are only adopting features from the other. To make matters worse, you can't easily (at all?) choose to install your own OS on a phone, so over time as the "losers" drop off we're going to be left with 2 phone plaforms that are more or less the same and haven't made any major UI changes since they became successful. And there will be no out for us who want something different.
