If they could deliver me a quad venti latte in 12.5 minutes, then I'd be impressed.

But in all seriousness, generally the only thing that has ever been disappointing about ordering from Amazon, is the shipping times. Any time I've ever had to call Amazon because of an issue, I've been impressed with their general attitude toward me and their willingness to fix or go beyond what my original issue was.

Having said that, they seem to have some smart people working on logistics for them https://www.youtube.com/watch?v=gcXoj_UBXv8

So it only makes sense for them to move toward the "last mile"
