Take photos with your iPad -- as long as you have an iPhone, too
Put Camera A, which costs a dollar, on your iPad. Put Camera B, which is free, on your iPhone. Turn on Bluetooth on each device. Bada-bing! The input from your iPhone's camera will be displayed on your iPad. The button to take a photo is on the iPad app, but you can save to either (or both) of your devices. Just a cute little perk for the big Apple spenders out there. I wonder if a video version will eventually show up, too ... maybe over wi-fi instead of Bluetooth?
