The giant Consumer Electronics Show opens tomorrow in Las Vegas (not counting the Bill Gates pre-show keynote at 6.30pm tonight), and previews generally reckon that wireless devices will be prominent.

Meanwhile, the US-based Consumer Electronics Association (CEA) has some sales predictions for the $100bn business. Freelance Ashley Norris will be reporting from CES for Guardian Online.
