My last "in store" repair at an actual Apple Store took a week and a half.

The times I've had a "return to depot" repair, I pretty consistently had the machine back in my hands after two or three days. So none of this seems bad to me... anything Apple can do to improve their repair experience is a plus.
That said, my experiences with Apple's service over the past decade is getting eerily similar to what I experienced with Dell 10-15 years ago. Around 2000 Dell's service was amazing - but, by 2004-2005, their service (and most of their products) sucked. I really, really don't want Apple to continue down that road.
