Wow. Such a slick little system. I am surprised that I did not venture down this path a long time ago. For about $60, you can have quite a flexible little system. Best of all, its designed to run on Debian Linux. For me, the cost includes the Raspberry Pi Board, a basic plastic case, and a small SD card.
My first use of the system is to setup as a multimedia server within a vehicle. Using UPNP to service multiple devices over any desired platform is the end goal. More on that setup as it develops.
The second use that I immediately wanted to use the system for is XBMC. XBMC is a media “front end” that can be used to connect into UPNP, SMB/CIFS shares, as well as download free content from offline such as HGTV. The latter is a perk for the wife since we no longer subscribe to cable/satellite or similar.
There are many other slick uses that these systems can do – anything from temperature sensors to security cameras. I certainly look forward to sharing my experiences as I venture into this product.
