A lot of the iPod docks on the market are pretty lame, failing to capture the elegance and style embodied in the actual player itself, and I've often wondered what an iPod dock would look like if Apple actually designed one themselves.
This concept from Bluelarix Designworks in Holland is probably pretty close, with a basic form that strongly resembles the current iMac design. More than just a simple iPod dock, the Wireless Music System streams files wirelessly from your computer, and includes a built in hard drive, CD/DVD player, and an Internet radio tuner. The entire system is controlled using an Apple-like remote control.
Right now it's just a concept, but hopefully this one will make it into production.
