I think it has come close to what we'd expect. Personally, I am really impressed.

The eclipse plugin has made Dramatic improvements in the last couple of versions. ADT 11 of the plugin has some great stuff mentioned in this video: here.
here is a good summary of the changes / improvements made in ADT 11. You'll also need version 11 of the sdk tools, available here.

I think the options are the eclipse plugin (ADT) and DroidDraw.
