I happen to disagree. It gives the iluusion of being faster because it scrolls faster than other browsers. This is because it scrolls more. More than other browsers. More than other applications or what is considered the platform default.
This is particularly annoying when you want to scroll with any kind of precision. Including other scrolling glitches, this becomes annoying pretty fast and I would In fact say its scrolling is by definition broken.
As for speed. Tried zooming on any particular with a reasonable amount of content? The entire browser freezes and is on hiatus for several seconds.
Chrome (WebKit) appears to render pages quickly too, which is important for normal browsing. Would be nice to see some tests of this, like the iPhone vs Blackberry ones.
