Hi, I like David's slim scrollbar, I think it's more attractive than the usual windows toolbar. I also agree with David's point that a standard window toolbar may influence people away from realizing that they can scroll a Timeline along the time axis.
My 2 cents on the issue are: 1) The scrollbar should always be visible if there are more events than can be shown on the available tracks. It should be usable as a handle for moving the Timeline since its affordance is to act as a handle. (Affordance is a UI term. An object's affordance is the behavior that we expect from an object, given its appearance and context.) 2) I think the bouncing off the top and bottom of the band effect is great for when the touch gesture is used on an iPhone, iTouch, or some of the newer Macs. But having it occur as the result of a mouse-interaction doesn't feel right to me. I'd appreciate some way to turn that behavior off and I don't recommend it as a default (except when the browser has a touch interface). Note that Timeline works pretty well out of the box on the iTouch. Enabling the Timeline to be scrolled vertically really solves one of the few problems with Timeline on an iPhone etc. The only other issue is to change the bubbles' show/hide UI when used with an iPhone. That's on my list.

I think people ain't used to scrolling horizontally as much, so if vertical scrolling were any more emphasized than it is, then that might totally inhibit any hint that horizontal scrolling is possible. (A native vertical scrollbar would really emphasize vertical scrolling.)
