The UI looks really nice and modern in everything but the icons, it's so jarring going between this fresh looking UI, then seeing these dated looking icons every time you go to the home screen. Why do they still do nothing? Why can't they animate? Why can't I change their size, hide the ones I don't want down a layer like Android, resize them up into live tiles like Windows Phone or Widgets like Android? Why can't I put them where I want? Currently they just sort themselves to the top left. Where the icons really look bad is on the iPad, you have all these screen estate and the same amount of icons as your phone. You've just got massive gaps between icons and it looks crap, why doesn't the tablet version of IOS have widgets or live tiles at the very least? The battery argument doesn't fly with me, my Windows Phone and Android both last way longer than my iPhone and Windows Phone's is so efficient with them. These icons are the main reason why I do not like IOS as much as I should do. Apple really need to modernize them and give you more control over customization. The best thing about android is the themes and launchers, you can download one and make your phone UI look however you want, even make it look like IOS or Windows Phone. I don't get why Apple are so against letting you personalize a personal device.
