To preface this, my only experience with Android is via NitDroid (I haven't used Sygic either).

Driving home tonight, running Maps/Navigation was a joy compared to using Ovi Maps. Easy to type in a location with the onscreen keyboard. It quickly found my destination (I typed YMCA and was presented with the 3 closest, selected the right one) and off I went. I Re-routing was quick and easy. There are several different views you can quickly select. You can also get the traffic view to show up as well.

Another nice feature was the street view that shows up when you reach your destination (you can also get it from a button on the nav screen as well).

Voice worked at lunch (very much a computer voice as opposed to human). It didn't work on the way home? Not sure why. More playing needed.

I have good T-Mobile 3g coverage, and did not notice it pausing to download more map tiles, ran smooth the whole time.

As I mentioned the trial bluetooth mouse GPS software kicks off after 10min, but only took a couple seconds to restart. Finding my recent destinations were right off the main Find Directions menu, very convenient.

It also appears to work with at least 2 of the 3 golf gps programs I installed (haven't gone golfing yet though).

Downside is you need a data connection to use it. If Ovi Maps wouldn't require a data connection (despite having all the info it needs to search) it would at least be semi-useful where you don't have service. Since it does require a data connection, NitDroid beats it hands down.

I keep wanting to write a review (but I'm sure you can find plenty of those), so I'll just say it was pleasant and easy to use, did what it was supposed to (or at least what I expect of a Navigation app), which is far more than I can say for Ovi Maps.

If Ovi Maps doesn't get an update (either via PR1.3 if we ever get that, or at QT that we can run), I'll probably delete the US maps (almost 1GB) regain that space, and boot over to NitDroid for my Navigation needs. Major bonus when calling and gps work in NitDroid (and I'm sure they will at some point).
