What does this thing do?
They say it's like a pocket NAS that you can move anywhere and anybody can easily share files like Dropbox, but then it only comes with 512MB storage? So I am very confused.
Can someone explain in simple terms, what this does and why I (as a Dropbox user) might be interested.
Thanks.
You could run FreeNAS (v7, not sure about later) on that. Not sure if it's worth it for a single drive device.
What does it do?
It's a headless computer, in a tiny form factor that sits on the mains socket, with a drive bay. You use it for whatever you'd use a tiny headless computer for. The low power requirements make "always on" acceptable; thus things like torrenting or file serving or etc etc are okay.
Compare this tiny low-power device running a Linux distribution for file serving with that old desktop - bigger, uglier, hotter, more power hungry.
Then you have access to all the files in those drives via the web browser or via iPhone/Android apps.
You also can sync your files to this plug device by installing a client software on other computers (much like dropbox) but your are files are always private and never stored on the cloud.
