Sure, Ring Mouse sounds like something you might catch from an out-of-control rodent population while on vacation in a foreign country. And yes, we'll admit that that the whole concept sounds a bit awkward to those who have spent their entire computing lives using more input devices, but we've heard some compelling feedback from those who've actually tried Genius's wearable wireless peripheral, and it turns out the thing is actually usable. Now you can get in on that action, seeing as how the company just announced North American availability for the wireless peripheral. For $70, you can get your hands on -- or, rather, in -- one of these things, if you're a Windows user. Of course, you could use it for an engagement ring; just plan on being single for a very long time.
