Target in the US have integrated Virtual Earth into their store locator section of the website. It looks beautiful and is extremely easy to use. They've customised the push pins to be actual targets that represent stores in the area and also have changed the look and feel of the pushpin notes (hover over a pushpin) to suit the look and feel of their site.
Setting directions is also extremely simple to do - WOW the more I play with this the cooler it gets. Check it out for yourself here:
One thing they do miss though is the birds-eye view which gives an isometric view of the area - maybe one for version 2?
Hat tip to Robert McLaws for this one.
