To be honest, i greatly despise widgets. My Nexus 7 (when on Android) was bare of widgets other than a clock widget. My last phone had widgets and again i only used a clock one.
I'd rather see Apple make new features or add functionality to old ones (Like fully integrating Auxo or home gestures) than widgets. I mean if we have widgets then what's the point of apps, and vice versa? iOS was designed around the apps, not the homescreen. Sadly this is why I dislike Android; People focus too much on random flashy features that are cool but get old after a few months, rather than a strong app system. I mean Windows Phone 8, while only having like 150,000 apps, at least focuses on making apps the best they can be. I mean I dislike Samsung for their poorly built phones and overaggressive marketing, but at least they are trying to make new features that are actually useful (but also throw in a lot of pointless features)
iOS just needs UI improvements, better app APIs, and new features that are actually worthwhile, rather than widgets.
