> The advantage of moving sideways is that that's how every reading experience a user has ever experienced works, outside their computer.

Most of your customers are comfortable with the default scrolling experience. Those that are not are older; they are not your future. The fact that you have to include navigation instructions for your page shows that you're breaking expectations.

> For instance, what you are calling lag is the animation. Most people find computer navigation hostile because things move around and they don't know where they are going.

I was actually referring to the lag I experienced when testing the site on an iPad. The scrolling is jittery, it is pretty smooth on desktop Chrome though.

> In the case of scrolling, I find scrolling long documents a hostile user interface. It requires a great deal of user interaction and minute control over position. Pagination simply requires "next", "next", "next". I don't think every web site should work this way. But for long form content, it works a treat.

We've had a solution for long documents in HTML forever: the fragment identifier. I've recently seen a few clever sites use a fixed position div to provide a table of contents that updates as you scroll down the page. I wish I could find one; the affect is gorgeous, and still conforms to the normal web UX (and degrades gracefully).
