I just returned from las and went to ces on 1/8-1/11. There were lots of people, but the number of exhibitors was down a lot from last year. There were large empty spaces in the Exhibition Center. I stayed (and gambled) at Paris; there were very few people playing the slots--but ces attendees were probably there for the show and not gambling.
Agreed. CES (and in the past Comdex) weren't good for the casinos, although you would see sexed-up shows sometimes.
The strip clubs, though, do big business.
