Apple has really been racking up the patents lately, haven't they? Most of the time, they don't really amount to much, but the thrill of anticipation for Apple's next generation product is pretty much spearheaded by these black-and-white blueprints that make their rounds on the internet.
Case in point: Apple has patented a "handheld device" that uses capacitive sensors to recognize who you are based on the way you hold the device. The device would adjust itself based on the way your fingers are situated and your grip. The device might also be able to generate buttons right on to the chasis (we're visualizing that it's like the way that Android phones have buttons that fade in and out), depending on which hand you've got it in. There's not much else beyond that, but the idea is that there is no on orientation for a handheld device, and it gives the mantra that you're "holding it wrong" a whole new meaning.
Anyway, all these patents are just teasers for a better device in the end. So hold on to your horses and don't start salivating just yet--the patent is still a patent, after all.
