Jarvy - Yes, you still have to do the customs declaration (nope, I don't have a live chicken in my handbag), and people who previously had to fill in the normal I94 (not the visa-waiver green form) have to do that too.
It's nice not to have to fill in the form, but there was still a lot of confusion about it when I went through in mid-July about who needed what: I think the I94-W had been abolished as of the start of July.
Edited to add: Paxboy: I had a customs guy in SFO try to matchmake me with the guy behind me in line (I guess because we were both travelling solo), and then when I wasn't taking the bait, try to give me his number... I wasn't going to test out his sense of humour by giving him the slapdown I thought that merited!
