ThinkGeek offers the PTeq USB Pregnancy Test gadget. This is a world's first.

After you exposed the USB Pregnancy Test to pee you have to plug it into an USB port to see the result.
While most home tests can detect a level of 15-50 mIU/mL of hCG, the enhanced methodology of the USB Pregnancy Test Kit can detect 5-50 mIU/mL, and will show you the exact concentration via its friendly onscreen interface.

In addition, the LCD display on the device itself will light up and show you the symbol of a baby, no baby, or multiples and your Estimated Delivery Date based on the concentration of hCG, hCG-H, and LH in your urine. So you can clear your calendar in advance.
The pTeq USB Pregnancy Test sells for $17.99 on ThinkGeek only today on April 1st.
