For a purportedly doomed manufacturer of magnetic storage, Seagate sure is spinning some interesting ideas these days -- last year, we got modular, upgradable cables, and now the company's testing external hard drives that don't need pesky wires to function. According to filings, the Seagate GoFlex Satellite not only plays the network-attached-storage card with built-in 802.11 b/g/n WiFi, it's also got a 3.7V battery inside its case... making the product's name somewhat apt, don't you think? According to a leaked description, Seagate's also planning a companion iOS app called "GoFlex Media" to let your iDevices stream content directly from the device. Mind you, none of that means you won't be able to dock with your Satellite the old-fashioned way -- FCC docs also mention a USB 3.0 cable that delivers data and power simultaneously.
