I never used one on the previous 3 versions of this phone, especially on the touch pro since i got a new one every week or so, HOWEVER those tiny little scratches that you keep running into with the stylus or your finger seems to make them bigger and more annoying after awhile! Therefore didn't even touch the new tp2 out of box until i put it on!
As far as responsiveness you can change your settings to make it more sensitive if you "think" it seems less responsive. My screen protecter came with it no fancy one and I have not noticed any problem with responsiveness.
