DISADVANTAGES. EXPENSE: A PDA is definitely more expensive than a hipster
PDA. Although you can now find basic palm PDAs for
less than US $100.
FRAGILE: PDA is more delicate than a Hipster. If u drop your Hipster from a few feet in the air
pick it up and continue using it without worry, you cannot do it with your PDA.
