"Bridge can do most of the database management that lightroom can. Don't get me wrong, I'm all into LR but I ask it since I care what others think."
Well, they're simply ignorant, aren't they? Crash a drive, and now tell me how much use Bridge will be as you restore from backup? We're in chocolate soldier territory with Bridge, while Lightroom will still list all the files you need to restore and where they should be. Or let's look for all pictures with 5 stars - I'll leave someone else to run that search in Bridge on 75''' pictures on 5 different drives. I'll do it in a few seconds. etc etc
As for the comment about ACR, it's way off target. If one is being harsh, one might characterise Lightroom as Adobe's defence to the threat that Aperture posed to a big chunk of Photoshop's market. The "genius" belonged to those who introduced Aperture because until then, Adobe hadn't believed there was any market for a tarted up ACR plugin.
