Why do people like touch screens so much?

well in my own opinion it just fells beter and you can do a lot more things with touch screens. for instance i have a iPod touch 32gbs and you can tilt it to the right and a little monke in a ball rolls to the right or playing taptap with just the touch of the screen. also you seem to interact more with a toch screen then a normal item wether it be a computer video game or iPod.
