Nexus 5 with KitKat: hands-on impressions

Why oh why cant google fix the scrolling performance?

"Speaking of rendering, the old bugbear of Android has always been scrolling performance. Especially in Chrome, there's always been a sense of lag that seemed completely out of place on top-tier devices. On the Nexus 5, we're very sad to report that the situation doesn't seem any better. There is still not a one-to-one relationship between your finger and the screen, and it's still crazy-making."
