Tom of tomment pointed out via a comment on my post about Yahoo!'s updated imagery that Microsoft's live.com has good images of Edinburgh as well. These are the best I've yet seen in any web based mapping platform.
Note that I couldn't actually use local.live.com in my firefox browser, but could use it fine in plain old mozilla. Not sure if that is due to some local glitch or not.
Update: Exploring more with the local.live.com site I find that Fife itself (north of Edinburgh, the region of Scotland where I grew up) has wonderful coverage and detail. The images are pretty recent too - I know this because I can see the alterations that my parents made to their garden a few years ago.
