I've been using the free Waze & MapQuest apps locally just to see how they do with routes I'm familiar with. Some observations:
? Waze has the better screen. The fonts are larger, it gives traffic alerts & ETA. MapQuest doesn't work in landscape mode.
? MapQuest is faster & better at recalculating a route. Waze seems to want to stick to their original route and tries to force you back to that despite a better alternative.
I'm going to continue testing both apps, but right now if I were to drive somewhere I knew nothing about, I'd trust MapQuest to do a better job of actually getting me to my destination with the least fuss.
One thing I'm still wondering about is how these GPS/nav apps work in areas with spotty cell coverage. My 2.5 yr. old TomTom will sometimes lose the satellite in downtown SF or deep canyons, but not when I'm way out in the boonies. I don't think I'll buy a new dedicated GPS device, but I'm also going to keep the TomTom in the car just in case.
