I use a PPC (currently an Ipaq 5450) connected to my carputer with WLAN (PCI card in the carputer, built in to the Ipaq) and NetRemote. With Media Center 9 (from J.River - I wouldn't touch Micro$oft's Meda Center PCs with a ten foot joystick!) I have full control over all aspects, from equlizer and volume to the full media library. I can find any song in about 15 seconds...in a close to 40 000 tracks MP3 library.
