On May 1, Samsung Electronics will start selling its Q1 ultra-mobile PC (UMPC), the first of a new breed of handheld device that Microsoft and Intel hope will change the way people use computers.However, don\u2019t look for a revolution to happen overnight. "The opportunities are big, but I think the turning point is still in the future, not tomorrow," said Dadi Perlmutter, senior vice president and general manager of Intel\u2019s Mobility Group."We are now playing with the first wave of something," he said.Based on the Origami platform developed by Microsoft and Intel, Samsung\u2019s Q1 runs the Tablet PC version of Windows XP and boasts a 7-inch touchscreen liquid crystal display (LCD) panel and a 900MHz Celeron M processor. With a price tag of around US$1,200, Samsung expects to sell 400,000 of the devices over the next year.For UMPCs to be a success, they must be more than a slimmed-down notebook or large PDA. "If it is going to end up that way,\u00a0I don\u2019t think it will succeed. It has to be something beyond just an \u2018in-between,\u2019 " Perlmutter said.Samsung\u2019s version of the UMPC, which measures 22.7 by 13.9 by 2.6 centimeters and weighs in at 779 grams, is generally typical of what first-generation UMPCs will look like.As with any new type of device, these designs will inevitably go through several rounds of revision and improvement, Perlmutter said. "We ultimately want to get [the UMPC] lighter, smaller," he said, noting that these versions of the device will likely be available in two years.Eight hours of battery life and Wimax connectivity will also be important features of future UMPCs, providing a constant high-speed Internet connection, Perlmutter said. This combination of high-speed connectivity and the relatively large LCD screen will allow users to access information on the Web that\u2019s not viewable on the small screen of a cell phone or PDA, he said.Combined with technology that can tailor this information to a user\u2019s location, future UMPCs offer the prospect of interesting new applications, Perlmutter said. "I have a restaurant chain. You log into my website, and I know your location. You get the map on top of Google Earth, you could even get my menu," he said.Of course, this can also be done using a notebook PC. "But it\u2019s not realistic that I\u2019m going to take my notebook out of my bag each time I want to look for something," Perlmutter said. "But if I have device like [the UMPC] with instant-on, it\u2019s useful."-Sumner Lemon, IDG News ServiceFor related news coverage, read Samsung to Launch Q1 Ultra Mobile PC in May.Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
