Mundane laptops will also get a makeover. Expect plenty of buzz around a new Sony Vaio laptop, which the company says is "revolutionary" and will change the way users think about the products. It remains unclear if the tiny laptop is a netbook or a full-featured ultraportable. For power users, Lenovo is expected to show the ThinkPad W700DS laptop with two screens -- a first in laptops -- for people who want to perform multiple tasks at the same time.
Rounding off mobility will be smartphones with new operating systems, touchscreens and 3G connectivity. Many mobile phone companies are expected to adopt Google's Android platform, including Samsung, which may show an Android phone at CES.
Struggling smartphone maker Palm is holding a big event to announce its new Linux-based OS code-named Nova, along with new devices. The company hopes to use CES as a springboard to regain prominence in the smart phone market, where it has been eclipsed by Research In Motion and Apple.
Like past CES shows, televisions will grab the imagination of visitors as vendors fight to remain the centerpiece for home entertainment. CES 2008 saw the emergence of OLED screens with prototypes from Sony and Samsung, and CES 2009 could see further progress. In May, Sony CEO Howard Stringer said a 27-inch OLED TV would be coming, which could launch at the show.
Samsung showed a 40-inch OLED high-definition TV prototype in October, and larger screens may be on tap.
