I wish all of the buttons were at least on the right side, since I am right handed. It would be best if they were on the bottom like the iPhone, but I guess they wanted the address bar on top for sure ( which makes sense) and didn't want to put the buttons on the bottom because then there would be 2 bars taking up screen real-estate.
I wish Apple would at least make the button positions able to be moved around to where everyone can put them where they most like them.
