Longer legs
-other than looking sexy, you can avoid smelling awful BO in crowded places. Think about your nose stuck in someone else's armpit. Ewww.
Longer hair
-save cost for not having to have hair extensions just to look like LiLo ;)
Longer '000...' in our allowances
-this does not need further explanation.
Longer attention span
-to have good grades, you don't need to talk to imaginary Britney during class. LOL
Longer phone?
Longer free vibrator! HAHAHAHAHA
Kidding.
Longer screen means longer text that can be written in 1 page
