Western Digital‘s expanding their line to 1TB and 500GB drives in the My Book World Edition family, which means they have either dual-drive configuration and RAID capability, or just a USB port for added storage and an Ethernet port.
Sifting through the crap that is the horrible press release, the 1TB models can use that Gigabit Ethernet connection to connect directly to your router, which then allows you to access your data from anywhere without actually having to turn on your PC. Essentially a cheap NAS, these WD My Books could be a decent way to let your family members access your photos without going through something like Flickr.
