Software
So the Lumia, and the Blackberry get negative comments because you have to install their software to get video off of the phone. No mention of the required iTunes infestation in the iPhone review. I also think more needs to be made of the hideous rolling shutter effect; it's very pronounced on the sample video from the Nexus and quite a few others.
All in all though a pretty good round up, I'd say the iPhone's lack of continuous autofocus works in its favour. Some of the other phones, particularly the Lumia seem to struggle with constantly refocusing on the wrong thing. The sensor size of these cameras means that apart from extreme close ups the depth of field will take care of most focus issues for you.
A bit disappointing not to see some gig footage shot with each phone. I find this is a huge test for a phone, flashing lights are tricky for almost all of them and the ability of the onboard microphone to deal with a really loud sound system should have been mentioned.
