I hope you wont laugh at me but I prefer physical buttons. They just seem better. Havent had those since the G1.
The physical home button is like THE thing I miss most about an iPhone. Being able to push the home button to turn it on as opposed to having to press the power button was a big plus to me. Also, I really liked the power button location on top. On the gnex, I have a hard time putting it in standby because when I press the sleep button I'll also end up pressing volume up or down. Very annoying.
