most all wheel drive cars are slower off the line than their two wheel drive counterparts.
That's plain wrong. All else being equal, AWD is always faster off the line because you are usually traction limited at launch, and AWD allows you to hook up all your tires when you dump the clutch. They are slower afterwards because of the extra weight and drivetrain losses, but no doubt they can take off like a bat outta hell from a full stop.
From the release: "Panasonic Digital Still Cameras now include a technology that can identify a genuine Panasonic battery. For the protection of our customers Panasonic developed this technology after it was discovered that some aftermarket 3rd party batteries do not meet the rigid safety standards Panasonic uses."
The firmware warning is quite clear as to what it does: "After this firmware update your Panasonic Digital Camera cannot be operated by 3rd party batteries (non genuine Panasonic batteries)."
