Nexus 7 screen snaps back

Just got a Nexus 7 and I love it to death. It has one annoying quirk, though, which Josh noticed in his review. When flipping through the home screens or the app and widget screens, instead of scrolling to the next screen, it will snap back to the screen I'm trying to flip from. It does it pretty regularly. It doesn't happen if I do broad swipes with my index finger, but it happens all the time when I do quick short swipes with my thumb. I would have thought that the software would have some inertia programmed into it so that it recognizes my thumb swipe as a desire to change to the next page. Anyone else encountering this problem?
