i see these posts often. and as a gadget geek myself, let me ask OP a question: what is it you think the iphone is missing?
mostly I have heard 'screen size', which to me is asthetic. someone may want a 6-inch phone. i don't. so when you say they aren't innovating, then what are you asking? what are you thinking that the iphone should have?
personally, i think the front facing camera is a crime, it should be at least as good as the iphone4's camera at this point. but that's not innovation, that's just preference.
is it because the body looks the same? we need to change the appearance every few months to be 'innovative'? i think the iphone 4 was amazing looking, and prefer it over the 5. but, again, preference.
here is something i would like. make a 'documents' gallery, like we currently have a photo gallery. let me keep PDF's, docs, pages files, whatever, there. and then let me access them at will by any other app. i don't need a file system, i just need to be able to edit something in my dropbox.
is THAT innovation? i doubt it. that's just applying one idea to another file type.
let Siri work better between commands. Siri, what time is the football game tonight? 'Redskins and Eagles play at 7.' Please email that to my dad. "what would you like to say to your dad?" connect those two so she knows i mean 'that' is the search she just did.
not sure that is innovation either.
so, rambling message aside, i ask again. what innovations are you searching for? what has been inovated elsewhere that you are looking for?
ps. controller API's are in iOS7, so i suspect that will show up soon.
