Good points. I should revise what I wrote to touch-enabled scrolling hardware.
With a scroll wheel, both fine and gross movements are more difficult. The scroll wheel has a fixed set of positions, and is optimized for scrolling a line or two at a time. I also have never liked the modal "scroll mode" that you describe.
With a magic mouse or scrolling trackpad, you get a much larger surface area available for scrolling, and there are more gradations. Inertia scrolling also makes it easy to scroll to the bottom or top of documents quickly: you can quickly "flick" to get to the bottom or top, which feels pretty natural.
As a result, I find I interact with the scroll bar a lot less on my MacBook Air than I do on my scroll-wheel equipped desktop. I'm not sure what the situation is like on Windows though.

Us poor Windows users have to hike few miles, find the cursor, lift and carry it on the back for a mile to get it to where we want it to, and then place it there. After all that, the page moves an inch.
