Seagate Wireless is another 500GB portable drive. Aiming to cure the limited-space woes on phones and tablets, this multihued model creates its own network, so there's no need to worry about finding WiFi along the highway. Files are managed via Seagate's Media app for iOS, Android, Kindle and Windows 8, and what's more, stored media can be beamed to a big screen with Airplay, Chromecast or with the company's app for smart TVs and Roku players. Expect five color schemes when the $130 Wireless hits shelves in February.
