Hi Dowdle, thank you for the nice comments and feedback - I really appreciate it. Please let me or the folks in #anaconda (freenode) know if you run into any issues you don't see getting addressed. If there are particular scenarios you've tried that aren't working out, that is good feedback - especially if you can help walk us through the scenario. We have been modifying the design as we go in response to user feedback, so it's really helpful to have it keep coming in: we absolutely do listen and take it into account.
At this point in the release cycle it's not really possible for us to make major changes, but once Fedora 18 is out we're planning to conduct a usability study on the interface, as well as comb through the user feedback from the F18 release. We'll plan and make modifications to the design based on that data, so you'll be seeing more blog posts and such asking for that kind of feedback.
