A mouse with a scroll wheel and all the comments fully expanded on one page and a high-resolution monitor showing lots of lines of text at once.
The page-down button is a distant second. I find using a laptop without a scroll-wheel mouse mildly displeasing. A laptop with a screen that can show a quarter of the amount of text that my desktop PC can do is infuriating.
Are you trying to read long threads on a smartphone or tablet, pawing at the touchscreen with your finger?
