I have gotten used to my 3 Performance's acceleration, but in the opposite way...I came from an S Performance, and the 3 felt awfully slow when I first got it just over a year ago. I knew the 3 would be slower and I was prepared for it logically, but emotionally I was disappointed with the 3 at first.
But I'm now used to it and really happy with the 3. (Now my wife's X 100D...no, that isn't quick enough. At least not anymore...it's way quicker than any ICE I ever had, so I clearly have gotten used to a certain level of acceleration). Sure, every now and then I'll wish I had a little more, and I sometimes kind of miss the S's launch. But not really that often...the 3's acceleration is nice and smooth; the S at launch was almost violent. I loved the S Performance when I had it, but now I'm perfectly happy with the 3 Performance. I may have another S some day, but I don't think it will be because I'm chasing more acceleration.
