I use LR everyday & I'm finding that for most of my professional assignments I can do everything I need in the way of post-processing within LR, only using Photoshop for things like:
--When I need the power of layers
--adding text
--detailed selection within an image (Photoshop offers so many ways to select)
--combining pixels from different images, such as making an animated GIF, panoramas, or HDR
Without leaving LR, I can make adjustments to the images (non-destructively), create collections of topic, do a slideshow, make a printed book & create websites and upload them.
There is a learning curve, especially since some of the best features don't stand out in the interface (I'm particularly thinking of the targeted adjustment tools)
The fact that LR is a database of all your imported images is often overlooked. Thus you know where all your photos are, even if they are on a disconnected HD. You have to get used to moving images from within LR, not by using the Finder.
Here's a link to a Keynote presentation I use in my classes, comparing LR & Photoshop:
