Like a previous comment stated, I print a limited number of keepers from a shoot. I cannot see the appeal of LR2. I owned LR1 and was hard pressed to find anything it could do that I would need to leave CS3 for. I actually erased it from my computer. I got CS4 and love it. I do a lot of localized tonal and color editing and find that all the broad tools and localized tools that LR2 advocates brag about are already in ACR or can be taken further in layers, smart objects and NIK plugins that LR2 does not allow at this time. I purchased the LR2 with the CS4 pre-release and found the process of having to import all images to be of no use to me personally. I am not saying it is bad. I have done non-destructive editing on PSD files as smart objects and with layers while having the original CR2 files as a backup for years and am puzzled that the LR2 advocates act like this is the first time we can perform non-destructive editing. Just don't feel afraid of layers. Lynda.com has excellent training that can teach you to make CS easier to comprehend (same for LR) and you will find that when you find out how much more you can do, you will start to do more. Sometimes doing less is truly better, but sometimes people advise doing less because they are out of their comfort zone.
Everybody seems to voice the mantra about not having to leave LR to go to CS, but I seem to have the opposite situation in not really needing to leave CS to go to LR. I saw the printing video by Michael and Jeff and while I got a tremendous amount of info from them I do not find the ability to waste the hard paid for paper size on extra wide margins to be of use to my personal workflow. Both of these guys have printers that make table cloth sized prints and so perhaps this is an option for the lucky few who can afford such printers. For the money I had to take away from other facets of my life to purchase a 17x22 printer and supplies, I want a 1/4 inch standard border on the image as large as that paper will hold.
Admittedly the keywording in LR is a little more advanced, but I have been able to track all of my images, key them with templates and manually and use templates to imbed metadata with no real pain in CS. Once again, what it the superior option. I don't find the $$ for LR to give that much better rating or tracking. I have devised a logical and easily trackable set of folders in bridge and never am at a loss to find any image quickly.
In fairness to the pro-LR folks, it seems that when I talk to someone who loves it they are wedding, portrait, wildlife or sports. These (and probably other) subject/markets seem to need a greater ability to almost never micro-manage an image and perform overall/global changes to hundreds or thousands of images at a time. That would truly be a LR strong point. For the person who shoots 500 still life images and then enhances every inch of 2 or 3 keepers CS wins the race.
