PNA still have it uses, and personally I have PNA running iGO8 that beat the crap out of Waze or Google running on android/iPhone; even give NextGen on android run for it's money. Ah, the PDA/PNA days where NNG hacking was starting (the golden age) The only thing that android have over PNA's is the price, I can get a 480x320 for $5 that rival any 480x272 PNA costing much more.

Those proggy may be free but they are crap compared to NNG/Navigon/Sygic(the older version). Case in point, my bro was using Waze (he swear on the accuracy of it) while I was trying to show him my NextGen, it routed him every way but the correct way. The look on this face was priceless.
