Broken Healer

LAS VEGAS, Nevada (CNN) — Every year, the International Consumer Electronics Show yields dozens of exciting, useful and just plain silly high-tech gadgets. Sometimes they’re even useful and silly at the same time, like a wristwatch cell phone.

The tiny, 3G-capable LG watch phone has a 1.4-inch screen but still packs a host of features.

Some products are in stores now, although many are due later this year and a few are still in the prototype stage. Which, if any, will catch on with consumers? It’s probably too soon to tell.

CNN spent several days touring the booths at CES, which ended Sunday. Here are a handful of gadgets that caught our eye:

LG Touch Watch Phone

LG Electronics made a splash in Vegas when it unveiled what it claims is the world’s first market-ready touch-screen watch phone. That’s right, a phone you wear on your wrist.

"You want to think James Bond, ‘Get Smart,’ Dick Tracy. It’s all that and more," LG spokesman Martin Valdez said. "You’ll never have to worry about losing your phone anymore."

The tiny, 3G-capable gadget has a 1.4-inch screen but packs a host of features such as Bluetooth, text messaging, still and video camera and a built-in speaker for playing music files.

LG hasn’t decided on a wireless carrier or set a price for the watch phone, which it hopes to begin selling in Europe and the U.S. this year. But won’t people feel silly talking into their wrists?

iRiver Wave-Home networking device

This minimalist, A-frame-shaped gadget wants to be your alarm clock, stereo, laptop, video-conferencing phone and digital photo frame all at once. The Wave-Home features a 7-inch touch download fantasy screen, webcam, built-in speakers, Internet access, MP3 music and video player, SD slot, USB port and more.

iRiver, a Korean-based company, hopes to get the device on the American market by the end of the year at a price — probably under $400 — that it hopes will encourage consumers to buy several units for many rooms of their home.

Sony Vaio Lifestyle PC

Smaller than a netbook and larger than a smart phone, this sleek device combines the best features of both. For one, it weighs 1.4 pounds and is small enough to fit in your coat pocket.

"It has a cool factor," Sony product manager Xavier Lauwaert said. "You go to a Starbucks and pop this out of your jacket, and people will go, ‘Ooh!’ "

The device is available in five colors and hits stores next month. A 60 GB model will sell for $900, a 128 GB model for $1,500.
