A minor feature of the touchscreen Sonys, at least the 700 and 600 [EDIT: Just read the 350 manual and it has this feature too], is
- stroke-and-hold fast forwards (or fast reverses) multiple pages. And when you release, you'll invariably find yourself on just the page where you intended. (Holding the Kindle's page forward button doesn't do anything more than the original press, i.e., one page forwarded.)
I call it a minor feature only in relation to the percentage of people who care about it. I'm in the minority that find the Sony's perfectly-behaving fast-forward highly desirable when reading material one tends to skip over or skim, like e-magazines and e-newspapers.
