CSI: NY - the best of the three, in my opinion. Will Danny & Lindsay ever get together? I still stay up with the original CSI: LV a bit too.
The New Adventures of Old Christine - This is the most overlooked comedy on tv. I think this show is hilarious and am so glad it's coming back for another season. You have to watch the episode with guest star George Costanza (what's his real name?) who plays Christine's gynecologist. So funny! Why doesn't CBS show full episode videos like everyone else?
CBS does have a great feature on it's website - full length episodes of classic television shows like Beauty and the Beast, Beverly Hills 90210 (totally have to watch those again), Family Ties, The Love Boat, MacGyver, Star Trek, and The Twilight Zone.
