Not to mention that:
1) Screen size is a personal preference, bigger != better. And even if it was so, Apple is preparing a new iPhone with a larger screen to be shown in June's WWDC according to all rumors.
2) Price is irrelevant if the devices are not comparable.
3) The iPhone regularly beats all other phones in camera reviews. If it's worse than anything, it is marginally worse. And after you get your photos in, the iPhone has crazy good apps for managing them, from VSCO and Camera+, to Photoshop and Lightroom Mobile.
4) And all that are for last years model. In less than 2 months there will be a NEW iPhone announced.
