Bing map also download the same offline map.
Bing map is way better with nice quick direction button, which is easier to use than all other competitors. The traffic actually works on Bing map, Nokia version is not working. Bing map open up like 30 times faster. Cannot even time Bing map because it opens up right away.
And most of all, I hate OEM cripple Windows, period. If want to install Nokia map, that is my choice, not forced to cripple my OS.
