It looks good, and the API is now frozen so module developers can get going before the final release.
A lot of the strength of Drupal comes from the modules and until they are on D7 it won't have a huge amount of benefit over D6.
The architectural changes are good and the api changes generally seem to be a step in the right direction. Personal favourite is RDF in core.
