Funny thing about MyLaps - they didn't bring anything original to the table. An RF tranponder is about 70 years old, and miniaturized versions are decades old. There are open-source programs out there that do timing and their receiver box/pc interface isn't exactly new or unique. It's a radio receiver that has a loop antenna (You AM/Shortwave/HAM guys might know this) that transmits information packets to the PC by a serial protocol over either USB, a serial port, or a 10BaseT connection. Hardly anything groundbreaking and certainly not worth the extravagant cost.
