Olympus viewer 2 question

I have not installed the Olympus viewer 2 because I have already Lightroom 4 and Photoshop CS3. I am going to upgrade to CS6 in a week. Do you feel I am missing something by not having Olympus viewer 2 ?

I f you have experience with Olympus viewer2, do you feel it does something that LR4 of CS3 cannot do ? Am I  missing something ?

Thank you for your comments.

Bernard.
