I've also been a great hater of Acrobat Reader on my Vista machine, and used to use some alternatives like Sumatra. But lately I've not noticed that it seem to work nicely, so either some upgrade has significantly improved its speed or my brain has adjusted to it. Could be both.

I found Sumatra PDF was viewing quite a lot of things (transparent images and similar) totally wrong, which made me go back to Actobat in the first place.
