Pogoplug — How it works
Pogoplug is one of the most talked about new devices at the big CES show in Vegas this year. $79 gets you a transformer sized device you plug into the wall. Attach an ethernet cable into your router (supports up to gigabit Ethernet speeds) and plug in any USB external hard drive.
Not only can you share files around your home network, but you can choose to share files over the internet through their website.
You can store files on the drive and e-mail the link to your friends and family for easy access. Seems like a great way to share photos or home videos.
