Sounds too good to be true

I found this via SlashDot this morning. While it sounds amazing, I'm not sure I'm convinced before I actually see this device in action. I remember seeing a similar article at some point, about a storage device that could work as a harddrive, but functioned as a flashdrive. They claimed a lot of different things, and it all seemed really promissing, but like most other stuff like this, it seems to have disappeared from the face of the earth. New technology rocks, but it's always a good idea to have a healthy scepticism, and not trust in everything blindly :)
