In any case, there's no reason not to use your eDGe fully now, one way or the other. Were the company to disappear, it wouldn't mean your eDGe would stop working, only that once it "breaks" you'll have to buy another device. And no handheld device lasts more than a few years anyway in light of the incredible new devices that show up year after year.
