I'm a HUGE fan of Windows Live Mobile and use it religiously (I do have to commute up the god-forsaken hell-hole of a freeway that is the 880 at least a few times a week after all). I'm glad to see that Microsoft finally gets a fair shake, not only in the mapping department, but also in the mobile OS space. Ahem...and I quote:

So which is better? Without a doubt, Microsoft's was the winner.

Even just comparing the mapping and traffic capabilities, this matchup could have been a bit uneven. We were running WLS on a Windows Mobile phone, which gave it a "native-app" feel, because it was a native app. Google Maps on Java ran like Java always does. Painfully

Yee haw! Link
