As much as I love it, it may be too much software for some people. Every single one of the photos I decide to keep gets some sort or adjusting, sharpening, cropping, tagging, uploading to web, etc. And for that, it has made my life much easier.
But, If you don't shoot RAW, or aren't as obsessive about tagging/editing high volumes of photos, there might be easier and cheaper options out there.
And the final release of v3 should be out before too long (the beta has been available for testing for a while). So if you're serious about it, I would wait for the new version to come out.
