One thing I do not like about LR is you cannot import JPEG and RAW files of the same shot simultaneously, according to the Kelby book I am reading. So, since I shoot Raw + JPEG, there isn't a sensible way to import them together, that I have found yet. I am glad I found this out. Major problemo to me. I have the jpeg set up in camera to a likely setting, and sometimes just use it instead of the raw, but always want the raw shot for the real keepers. The jpeg settings in Canon cameras can be tweeked pretty good in a lot of cases in camera. So maybe I will just stick with CS3 until they change that flaw.
