Even before the iPhone drops and the vaporware Zune Phone materializes, music phones are picking up a little steam, with popular phones like the Razr sporting music playing capabilities. All these phones offer limited capacity though, so Seagate is introducing "D.A.V.E.", a 10 or 20 GB portable drive with built-in WiFi and Bluetooth for sharing media, and, one assumes, the ability to stream songs for playback.
Although it adds another gizmo to carry, the hard drive will be about as slim as your current phone, 2.5 ounces, and can probably live in your backpack without impacting communications. Bluetooth 2 will minimize battery usage for the drive and your phone; Seagate claims about 10 hours of continuous use. If done right it could be a good way to add capacity to the convenience of a phone player
