SURVEY: Is Drupal 7 ready for use on production sites?

I've built several sites using Drupal 7. I've found it to be easier to use from a setup and interface point-of-view, but I've also found it to still be very buggy. I'm getting pretty comfortable with what I need to do to get the functionality out of it that I normally need, but overall I think Drupal 7 still needs a lot of work. I find myself using modules that are still in development or waiting for other modules not yet completed. I like using Drupal 7, but using it has its costs.

What do you think...
