Problem: Apple is famous (or infamous) for locking down its hardware. With the iPad, the storage you bought initially--16 GB, 32 GB, or 64 GB--is all you're ever going to have, since the tablet lacks a memory expansion slot. And while Apple's iCloud is available as additional closet space, what if you need local, portable storage?
Solution: Seagate's GoFlex Satellite Mobile Wireless Storage is a battery-powered, 500 GB hard drive that streams documents, HD video, and other content to up to three mobile devices simultaneously via 802.11 b/g/n Wi-Fi. Priced at $200, GoFlex offers up to 5 hours of battery life, and 25 hours of standby time, says Seagate.
