Greg,

I will refer you to the PR Adobe Lightroom 2.0 Review from last August that I wrote for several of the 'details'. From added cameras with each version (currently 2.5 with a release candidate 2.6 for Nikon D3S cameras) to continued fixes and refinements the Lightroom product is positively evolving.

With Lightroom 3 around the corner (looks like after the first of the year now) being on ver 2 would probably save you another $200 dollars or so as the upgrade path is cheaper with Adobe.

Lightroom 2 added a lot of tools and functionality in the editing process including some brush functionality, gradients for adjustments and new and expanded meta-data implementation.

If there is something specific you want to know or the article does not point you in the right direction for, let me know!!
