i would have to say no to this because of keyboard shortcuts. pressing the "home" button returns you to the top of the page while "end" takes you to the bottom.
with a high end mouse with extra mouse buttons, i have "home" set as a button making surfing quite easy for me.
although i do see why some people would want it. on a laptop, it maybe hard to use those keys or maybe people are too lazy to use keys while just reading
