There have been other, similar devices around for some time that allow you to dump the contents of your SD card to a portable, internally-powered hard drive, but they've all been a bit sketchy in my opinion with hugely mixed reviews regarding their reliability. This WD offering, though, is pretty much exactly what I've been waiting for: a portable (backup) hard drive I can dump a memory card to, on the fly, without needing a PC to power and/or facilitate, the file transfer. Thank GAWD it's USB 3.0 as well...
The wireless option is just a big, fat bonus as far as I'm concerned.
