I've had a loaner S75 for the last 3 weeks, and can say that I really miss the phone key. One of the main reasons I can't wait to get my 3 back. My phone works about 95% of the time without taking it out of my pocket and waking it up. I was SHOCKED to find out that the Model S key fob had worse performance - there have been 7-8 times over the last week in which I approached the S and the handles did not present, I sort of had to tap on them for 5-10 seconds before they would open. And, I learned the first day with the rental that it is possible to lock the fob in the car if it's left in the cup holder. From that point on the key had to stay in my pocket 100% of the day, which is just one more thing to carry around.
Agree with previous post that it is nice for remote trunk opening and closing though, if that is important to you may be worth it. Or if you use summon a ton...
