thanks! what kind of content/load would it hiccup on?

  I've had some bad experiences scrolling through super high-resolution scanned PDF documents. Those cause beachballing for several seconds in between each page. However, this seems to be a known issue in Preview, and it happens on other, more powerful Macs. I haven't tried with a more optimized PDF reader. Otherwise, if you have a very busy webpage with a lot going on, (and ads going), scrolling might not be entirely smooth.
