Few places are more materialistic than Las Vegas, with its grandiose hotels and stacks of cash. But at last week's CTIA (Cellular Telecommunications and Internet Association) convention—which showcased several acres of upcoming cellphone and wireless technology—the focus was less on material goods than on what you can do with them. The exhibits boasted no gotta-get-it-now phone, but they did promise many ways to do more with the phone you already have. From file-sharing to postcard-making, the latest possibilities go far beyond mere talk.

It's a brave new wireless world, yet most portable-audio hounds are still tangled up in headphone cords. Soon, though, you'll have lots of wireless stereo headphones to choose from. The technology isn't brand new, but until recently it was too bulky and expensive to shove into the tiny, splurge-worthy gadgets we love. Expect to see three flavors of wireless earmuffs—Bluetooth, Wi-Fi and magnetic induction [see sidebar below]—rolling out between now and early next year.
