I think it was engadget's review where it was commented about the placement of the 'back' button on the browser. To remedy this, click on the top right menu option while in the browser and then select settings and then labs. Activate the 'quick controls'. To use - slide your thumb from the outside edge of the screen onto the viewable screen and up will pop a nice finger friendly menu with quick options that include a back button. So it's always where you want it. Killer feature.
