Bought the following:
USB cable for cell phone. Who knows what fun could be had?
USB bluetooth thingy. WHo knows what fun could be had? Even has a small antenna.
USB 2 hub - to power all this fun stuff. $20 on sale.
Too bad the firewire card I bought is a full-length PCI connector. $30 down the drain. Was hoping I culd use it for faster ipod sync, but that's okay.
