Every cloud has a fluffy exterior

I'm hoping this thing works. It seems to in a clunky way and I think once I understand it's foibles everything will be fine. I was looking for a NAS type system and came across Pogoplug. They do actually offer free 5Gb of online cloud thing that seems to work pretty well - I was able to share some files for downloading with someone the other day.
This pink thing allows you to have your own personal cloud using hard drives attached to it.
