Virtual Earth just gets better and better (again!)

It's not accurate though. If I look at my house right now, it shows as nearly completely overcast. If I look out the actual window of my actual house, the sky is completely clear. Literally not even a single cloud. So I don't know where it gets it weather information from, but it's not very accurate.

The current standings in the map wars: for my area, Google Maps has much better aerial images and street view images. Live Maps has birds-eye view, 3D buildings for some districts, and slightly better maps. Google Maps gives train info if you ask for directions (very useful), Live Maps gives driving directions which are wrong and don't line up with the roads on the maps at all. The Japanese localized version of Live Maps doesn't have any functionality for directions. Both allow me to search for Japanese addresses, provided they're typed in Japanese characters, however in Live Search this only works when using the Japanese localized version.

Yahoo Maps has the best maps by far, the most detailed information on things like restaurants and shops, both train and driving directions, and walking directions to the nearest station. It may not look as nice, but it easily wins in terms of functionality.
