The DigiMate III is useful for photographers on the go who need to dump their flash drives into larger storage without having to turn on a laptop or PC. The device fits 2.5-inch laptop-sized hard drives, which as of now are available in up to 160GB sizes—much larger compared to 2 or 4GB flash cards.
The DigiMate has USB 2.0 support, a 6.6x5.0 cm touch screen, a 2 hour battery life, and Windows and Mac Support. It fits SD, MMC, Mini SD, Memory Stick, Memory Stick Pro, Memory Stick Duo, Compact Flash I/II, MicroDrive and xD Picture Cards. There's even an external battery pack that's powered by 4 AA batteries available for separate purchase.
