thinner or faster hardware, you know. Some people like to bring legitimately innovative ideas to the show, such as this iPhonECG case, which does what its name suggests: it takes an ECG (electrocardiogram) reading of your heart's activity through a pair of electrodes and then communicates its findings to an iPhone 4 it can be attached to. We say it can be attached to an iPhone as communication is done wirelessly, so you'll probably be able to monitor your ticker's rhythm without the Applephone pressed against your bosom. Then again, maybe you like that. It's a free world, we don't judge. We'll be sending out our most hairy-chested editor to give this thing a proper test at the Las Vegas convention next week. Until then, scope out the video after the break.
