The Apple iPhone’s impact was widely evi

题目：

The Apple iPhone’s impact was widely evident (明显的) at the Consumer Electronics Show, as new touch－screen devices could be found everywhere.

The consumer electronics industry came unbuttoned in Las Vegas this week. At the annual Consumer Electronics Show, companies from around the world unveiled many devices boasting (以拥有…而自豪) touch – sensitive technology, rather than traditional push-button controls.

Motorola, Sony, and LG Electronics all showed off touch-screen phones this week. Microsoft Chairman Bill Gates praised and offered a touch-screen computer, the Surface, related to a flat panel TV for a tabletop. Even camera makers, such as Kodak，included touch-screen LCDs in their devices. Touch-screen tech has been in use for years，but the push to develop and weave it into consumer electronics gathered steam with the June introduction of Apple’s iPhone. “The touch-screen industry is really getting hot,” says Jennifer Colegrove, a senior analyst at iSuppli. “Since the iPhone came out, there are a lot of companies that did not have a relationship with touch screens before that decided, ‘OK, I want to make a touch screen, too.’”

The touch－screen tech ecosystem now includes more than 100 companies specializing in everything from smudge-proof (防污的) screens to sensors (传感器) able to detect fingers before they even contact the screen. Sales of leading touch-screen technologies，such as those used in mobile phones and navigation (航行) devices，are expected to rise to $ 4.4 billion in 2012, up from $ 2.4 billion in 2006，according to iSuppli estimates.
