sorry, not meaning to sound aggressive, just expecting a tsunami of people here tell my my reasoning is crap, as is usually the way in here
i've always use the finger as we had no choice. now, i have this hyper accurate pointing device at hand. super, fast efficient and accurate. much more accurate than finger precision imo. apart from the obvious accuracy some apps certainly benefit from the Pencil, i find general browsing faster and easier.
clicking bookmarks, scrolling through websites, organising mail etc etc. even tapping the home button and hitting keys on the smart keyboard is a fluid motion with it too.
infact, the only time i really use my finger these days is when the pencil is charging or those times the pencil is inoprable, which isnt much.
