When I bought it, I had a simple job for this product in mind, and it was to make printing simple.  My my wife's work computer is locked down so we had to use google cloud print for her to print from home and this device worked great for that.  Also the printer I bought wasn't an airprint certified, so I installed an airprint server on it and it works great.  Lastly I use it for a network print server for the house.  As of last night, I plugged in an external harddrive into the computer and now I am also using it for an ITUNES media server for my movies.  It works great for that too!!  Overall this little piece of hardware has been a fantastic buy for these things and I think that this device is a big money saver for me.
