Re: Samsung Note has a hard "Home" button unlike HTC ONE V, that
I have two android devices both pretty low end but they are tweaked with custom kernels and roms so they work alright. One has soft keys for home, back, search, menu, the other has hard keys for those four buttons. I extremely prefer the physical old school almost tv remote buttons really for only two reasons. It's hard to accidentally hit one of said keys by accident and not realize it, but it is easy to accidentally hit the soft keys and not know it. The other thing is dirt or oil, if your fingers are dirty the buttons may be unresponsive to normal presses, if you push hard or move your finger a little it will work but with hard keys even if the push the button with dirty fingers or even something else (pencil eraser) it works every time.
P.S. On the cyanogenmod roms i run one can enable or disable the camera or volume buttons to wake the phone from sleep, i disable these so the phone only wakes from the power button, way less pocket wakes.
