Solid HDD with good capacity for storage. Can be easily connected to your computer/tv via the USB port or to the network via the LAN cable. Can copy with speeds up to 35 MB/sec via LAN. Can access the data remotely from anywhere in the world.
If you use it via wireless (from the router) you will have trouble streaming the videos as this is too slow.
The phone is easy to install, looks solid and has an auto-update function for the firmware which I particularly like. I like the idea that you can connect more than one unit to the base which I did already and also you can use the handsets to call between themselves.
