The huge, annual CES (Consumer Electronics Show) tradeshow is under way in Las Vegas this week. And Apple isn't there, as usual. But, as usual, Apple is everywhere. That is, many of the products being introduced are simply ripoffs of Apple products. PCWorld has an interesting article about this "Parade of ripoffs." One of the biggest trends at the show is expected to be the new slew of "ultrabook" computers — all of them looking very much like the MacBook Air.
