I can't express how much of a joy and time saver Lightroom has been ever since I started shooting with my D40. What happened when I got my D40? I started taking a lot of pictures, that's what. While I was in Indonesia I was shooting over 300 pictures a day. There's no way I'd be able to sort through over 2K+ pictures from a week of vacation in any reasonable amount of time and get them processed without Lightroom.
And now they've fixed the biggest annoyance I've had with it in the new version: lack of support for Nikon's proprietary color profiles. It's only in beta right now, but now I can get my pictures to look as good on the PC as they do on my camera's LCD without a ton of post-processing. Want to see what a difference this makes? Check this out.
And that's not even getting into the other improvements (so much faster! support for multiple volumes!) and new features (that I've yet to really play with).
