Here's a nice article about her and her character from the NY Daily News:
Dr. Strained Love

to stop worrying and adore Kate Walsh

"So you're the woman who's sleeping with my husband."
With that line, Kate Walsh, playing Dr. Addison (Addy) Shepherd on TV's hit "Grey's Anatomy," click-clacked her heels into television infamy. It was two years ago, at the close of the drama's first season, and Walsh's Addison had marched toward her estranged spouse, Dr. Derek Shepherd (Patrick Dempsey), and the program's protagonist/narrator, resident Meredith Grey (Ellen Pompeo), in the halls of fictional Seattle Grace Hospital.
Addison was an unexpected face from Derek's not-too-recent past, and Walsh was an addition to the ABC show, which, with her onboard, established its signature love triangle - and then got some unplanned-for results.
Because instead of being just a black-clad, wronged wife with her hair coiled tight, Addison became a thinking woman's heroine. She, too, had guilt issues - she had previously slept with Derek's best friend - but was also sympathetic; a dedicated prenatal ob-gyn, she had come to Seattle Grace ready to make amends. And while the character flits between steely and humane, alternating some biting put-downs with a comforting bedside manner, the woman who plays her likes to break the mold in a very "Grey's" kind of way.
