The main camera's 8MP is comparable to the latest iPhones. The iPhone 5S has better auto focus, but the slightly blurry test shots taken with the Nexus still look better than what I often see on Facebook.
The Nexus supports wireless charging, though the charger is sold separately. If you get it, you can ditch the microUSB cable and simply rest the Nexus on the charger. The Nexus also has a chip for near-field communications, which helps with mobile payments and file sharing.
