I think the benefits pointed out by Antigratvity are fair. Here are a couple of random thoughts for what they are worth...

To put things in context, a 991 4s weighs about 3,150 pounds, so the 35 pound reduction is a reduction of about 1% of the car weight. I don't think it's anything you can feel in the seat of your pants. You can try simulating the effect by putting 35 pounds of groceries in your frunk. Then time how long it takes you to go 0-100 and 100-0. Then remove the groceries and do the same thing, and see if you can tell the difference.
All else being equal, I'd prefer to shed 35 pounds from behind the rear axle where the engine is located, and not from the front of the car.
If I thought battery prices were set to rise, or if I thought a 35 pound difference would be noticeable under anything but track conditions, I'd consider purchasing the batter now. But i don't believe either of those conditions are true, so I'll probably wait until my battery dies. Once it does die, I would give some consider the antigravity battery because the incremental cost of $600 is not THAT high relative to the price of the car, and if I'm going to shell out $300 for a new battery I might was well go all the way and spend $900 for the weight reduction, added life expectancy, and higher cranking power of the Antigravity battery.
