the camera improvements look great, but i'm honestly very surprised to see that they stuck with 8 MP for the 3rd generation in a row. i was expecting at least 10 MP but seems cramming a larger sensor in there isn't happening at the moment.
I think smaller quality photos are better than bigger crapper photos, I think Apple are going the correct route with this - the sensor is far more important, plus 8MP is perfectly fine unless you plan on printing huge photos or banners. To be honest I am glad it is 8MP because my phone is getting filled up with photos as it is. So I certainly don't one bigger ones - not until they bring out a 128GB phone - which I was surprised they didn't.
I think 16gb and 32gb 5c and 64gb and 128gb 5s but apparently not - it's the only thing stopping me from upgrading my 64GB iPhone 5 to an iPhone 5S at the moment.
