Several things to ask:

1. the map displayed in waze on N900 seems to be different (older version) than map on world.waze.com. Why ?

2. when started in portrait mode, waze will not fill the screen properly but it's smaller with black frame. When rotated to landscape and then back to portrait the problem is fixed. I think this was in previous version as well.

3. new GUI integrated icons into one big instead. So far I realized that there is also no longer displayed my GPS speed (had no navigation, just waze turned on) even that it is enabled in properties.

4. this new GUI also caused that when I want to report even (crash, obstacle, etc.) I can not do that by one simple touch but now I have to touch it twice - first go to menu, then click on event. For me this seems to be less comfortable then before.
