Just wanted to post a quick note about backing up the Raspberry Pi. After your hard work of configuring it the way you want it, don't forget to back it up! It's also a good idea before making any big changes. I know it's a pain, but worth it in the end. I didn't do it for awhile just because I was too lazy to shutdown the Pi and remove the SD card. Since my workstation is Windows 7 Ultimate x64bit, I use win32diskimager, which works really well.
