The original Xbox was what got me into openwrt. I was in college, got a hold of an xbox and wanted to play with my friends online. I could spend $50 or more on the WiFi adapter Microsoft sold, or I could spend like $25 on an Wrt54G and flash it with openwrt, connect that to my WiFi as a wireless bridge and connect the Ethernet to my xbox. Worked like a charm and I had a multipurpose device instead of a single use Xbox WiFi adapter, for cheaper.
