People don't want to have to read manuals and become experts on every task. They want tools to get something done so they can focus their limited time and attention on things they care more about.
I'm the kind of person who wants to understand how everything I touch works (and the kind of person that does a lot of video recompression and cares about quality and filesize tradeoff) and even I hate Handbrake's UI. Every time I set up a new machine I spend an hour or two looking for an internet guide to what settings mean what to configure a preset, and then I use that preset basically exclusively. I'd much rather have a couple of drop targets, one of which is "Bluray 1080p quality".
