You can indeed go precisely to top/bottom but while in the middle of the page you will scroll (shall we say) 20 rows at once while your screen only displays 3.

Swiping quick 3-4 times will instantly get you at the bottom (see in app-manager) so kinetic can replace a scrollbar while a scrollbar can't replace kinetic since you will not have any possibility to scroll slow enough if your list gets too long.

Sorry for being jumpy
