Usability 
Microsoft's Local Search (beta) which is very similar to the Google and Yahoo Local Search offerings came out in June 2005. Searches by keyword and zip code or address return a list of hits, selecting a hit gives a map and a link to driving directions. The quality of the local search seems good, finding most of the restaurants in my neighborhood, for example. Browser detection is used to vary the map's size from 110 x 110 to 217 x 217 px depending on phone capabilities.
