> I don't understand why anyone would prefer a volume slider to discrete up/down buttons. I almost never want to quickly slide to a specific volume, it's always "this is a little too loud" or "I didn't quite hear that."

Have you actually used the slider to get used to it? It requires a significant-ish slide to increase/decrease a full dot. And by significant-ish I mean it is easy to adjust it less than one dot.

That being said I used to think the same until I got used to it, I slide more than a few dots up and down all the time. I would not want to go back to taptaptaptap.
