Waze? Absolutely!!!
It is faster up to date than any other navigation system/device I've used so far.

Pros
• folks from different areas going to meet at a certain place? Travel "together" using Waze.
• See their progress
• help them by sending them your destination and they'll chose the same location.
• Slow traffic? Jams/staus? Accidents? Object on road? Car stopped? ...?

Waze will update you on these and many more issues way before other navigation systems or radio stations will do.
• Map error? Report it (with details). Usually within a few hours or days, it'll be fixed.

Cons (will Waze fix those?)
• when using different apps (as a passenger) while using Waze, Waze always "restarts" asking if I want to continue
• as friends or family are using Waze, but they're further away than about 1,000 mi, I can't follow their drive nor can they follow mine.
• While traveling international, no points will be produced
• While traveling international you're a baby Wazer
• While traveling international not all places you add/edit/modify won't show up on Waze

I'm sure (and hopeful) this will be solved!
The sooner - the better!
