It has replaced my flash drive, I can keep my school notes and design documents completely synchronized from computer to computer to device without having to do anything. Also I moved 200GB of video files from one computer to another across my network at 10Gbps in a few hours. Actually moving the hard drive and copying the files over would have taken less time, but now when ever I add a new video to my collection it moves over to my home server without any fuss. Plus backing up all the pictures I take with my phone straight to my desktop is amazing, not that it wasn't possible before, but I don't have to leak the metadata from the pictures every time I want one backed up anymore by using a third party storage provider.
