That's how detailed the images (click pic to zoom in) on Microsoft's
local.live.com are. Not all cities are there yet, but what's there is pretty stunning. The coolest thing is that you can rotate the image to view an object from all sides. Not as polished as Google Maps in terms of interface yet, and Firefox compatibility is buggy, but very exciting nevertheless. Judging by this pic of my dorm, the images are pretty fresh, too. The road construction was happening last spring. A similar pic on Google is at least a decade old.
