Map24 has been my favorite online mapping solution, after I discovered them as they won two Webby Awards in 2004. The vector based java plugin, which works with both Internet Explorer and Firefox, makes it the smoothest solution I’ve seen. Now they teamed up with Google Europe, so that when you search for a city
