I don't think I have low standards for performance at all. I use my phone quite heavily all day, every day. To suggest otherwise because of a half second delay due to animations to me, speaks volumes.
My point is our expectations with all the advancements in technology we've seen are obviously getting out of hand with statements like yours. By your calculations, you are losing 5 mins of productivity in a day due to the animations. I question whether or not you really are losing that much time. That would mean that for every single action, your brain and fingers react instantaneously which I just don't see as feasible.
Let me be clear, I'm not arguing against getting rid of the animations to speed up the use of the device (and for those few who it made sick). I think it's good that they got rid of them although it's too bad that they don't offer them piece by piece (parallax vs. zoom in/out). I personally like the zoom in/out effect but could do without parallax and would've liked the option to turn on one while keeping the other off. However, you don't see me crying to the heavens over it's lack of features, even if it is form rather than function.
I think the relation between the level of complaint in this instance vs the real-world implications aren't warranted. Saying that level of delay is "completely unacceptable" is overkill. It's not like you're waiting 10 seconds with the spinner going for an app to open up.
