On Screen or Nah??

Sup,

Once again, this time in ATT- my friends told me that they hated the Nexus 5 (Which I love) because of the fact the buttons were on the screen. I wonder do consumers really care that much about buttons on the screen? I prefer on screen, however I want to be able to change them to my liking. Strangely they love the LG flex but wanted it smaller and did not like the way the interface looks. Lastly......they actually love TouchWiz over sense ...then again I do to. Oh God what am I turning into...

Feedback?
