For minor tweaks and adjustments, I think this new workflow is far more effective. Of course, it doesn't hurt that lightroom is an impressively well written program for this task. Using it, I get the feeling that it's a project that has not yet succumbed to the pitfall of feature bloat (which, it could be argued, some other products by adobe have). It has a very clear purpose in life, and the team that created it wasted no time in meeting that purpose.
Yeah, I have lots of pictures of flowers. I like them. :)
