Ako, although may Note 2 ako na merong capable GPS function, parang gusto ko pa rin ng dedicated GPS. Pero on the other side, naiisip ko yun gastos on buying a dedicated GPS kasi kaya naman ng Note 2 yun navigation. So to answer the question, if you have the money to burn, then go ahead and buy a dedicated GPS. Pero if you don't have, then don't.
Tsaka hindi naman madalas gamitin ang GPS dito eh. Last time I used it was nung nag-Baguio kami.
