Pharos iGPS-500 - minute GPS receiver
Basically it's a super tiny SiRFstar III-based modular GPS device that can connect either via Bluetooth (shown left), or SDIO / CF / PCMCIA adapter (right, sans PC card adapter, of course). What doesn't really come across here, however, is the size of this receiver. It's basically compared to like $1.25 worth of quarters stacked up
