I just posted this in another thread. It may give you some of the information you are after -- it's from the Audi Glossary, UK Edition (which explains the spelling of "centre" and "manoeuvre" which the Pilgrims forgot on the way over):
The electromechanical parking brake has little in common with a conventional handbrake. It is resistant to wear, its braking effect is permanently constant and it cannot lock. The electromechanical parking brake is activated by pulling the small electric lever on the centre console, which replaces the conventional handbrake lever. The parking brake is released automatically when setting off. It does not have to be released manually even when performing a hill start. The integral starting assist function determines the selected gear, accelerator position, engine speed, torque, direction of travel and the vehicle's angle of inclination. This prevents the car from rolling back when the parking brake is released automatically.
The brake can only be released manually if the foot brake is depressed at the same time. In the event of an emergency braking manoeuvre via the parking brake, the vehicle can be braked considerably more effectively than with a conventional handbrake because in this case braking takes place via the normal service brake with the aid of the vehicle's electronic stabilization program (ESP) functions. All the benefits of the anti-lock braking system (ABS) and electronic brake-force distribution (EBD) are exploited.

Which makes me curious - if someone pushed hard enough while it was parked, would the ebrake release? Or does it only release like that while the engine is running? hopefully the latter!
Maybe I'm old fashioned but I'd still prefer a dipstick and a hand brake to the electronic versions. I'll admit though that not having the hand brake taking up space does make the center console a whole lot slicker

Some technical info to add:
-To change the rear brake pads or rotors, you will need a VCDS or similar to put the brake in "service mode"
-The brake servos are likely expensive to replace when they break, but at least you don't have to fool around under the car to replace the brake cables and adjust them.

The e-brake will only release if you push on the gas pedal. Great for hills and also solves the "I just drove 10 miles with the parking break on because I forgot to release it" problem.

Also note that the e-brake will only release automatically if you have your seatbelt on. If not, you have to manually release the e-brake (with your foot on the brake).
