CS5 Photoshop extended vs. Photoshop lightroom question

[DW Rare Coins]

Greetings! My name is Dave and I've been using PS 7 for years now and I've finally treated myself to the new CS5 Photoshop extended. It comes bundled in the Design premium and it should arrive this Tuesday, it's going to be my Christmas present to myself. I shoot a Nikon D7000 and D70s with a 105 mm Marco and my main use is to prepare sharp images of coins and other collectibles and I use PS to combine the images. I also do portrait photos and outdoor macro images of bugs and flowers, in addition to using my 400 mm zoom for bird photos. So I figured I could integrate all my interests with the new PS. However, while I was deciding on which bundle to purchase I was intrigued with Adobe Lightroom and I was wondering if there was any reason that I should also purchase Lightroom in addition to CS5. Or is Lightroom a slightly watered down version of PS, similar to Elements?
TIA

No not at all Lightroom is a very powerfull tool it is probably prefered over photoshop for photographers. It gives you the ability to multi process images ie if you have a whole album and you want it all to be in the same style ie colour correction sharpening some of the many photographic filters built into the program, You can edit 1 picture and copy all that editing over to the rest of the pictures in the album with 1 click.
It does have some basic editing features like spot removal tool graduated filters raw processing sharpening etc. What makes lightroom stand out is the amount of simplicity it is to use to develop your pictures even with the option to automatically upload pictures to numerous photo sharing sites ie facebook flickr photobucket etc all with 1 click. So yeah if you want to batch process images lightroom is a strong application. However apart from uploading to social networking sites there is not much you can do in lightroom that can not be done in photoshop. Photoshop gives you much more ability when it comes to manipulating images.
