Test-drove LR4 (and every version before it) - but even after the price drop, the software isn't for me. Reasons why I don't use LR4: don't need the library function, don't like this catalog importing nonsense (which though faster is still taking up time), and like the ACR interface better. No benefit for me in using LR4.
LR4 has more of a "real-time disadvantage for me: the short but noticeable delay where a blurred image is displayed while browsing through images when LR reads and displays the embedded JPEG, and then renders a new one based on the LR4 settings - and instead of making a smooth transition, displays a blurry version instead. I have a very fast computer and graphics card - but when attempting to browse quickly through hundreds of images, this constant sharp-blur-sharp and the delays involved drive me bonkers. BreezeBrowser for the screening and CS6 for the processing for me; am working on including DxO into my workflow.
