generation Windows Vista(TM) operating system (OS).

“High performance, long battery life, affordability and investment
protection, are critical selection factors for notebook PCs,” said Phil
Eisler, Vice President and General Manager of ATI’s Integrated and Mobile
Business Unit. “The latter-investment protection-has never been more
critical as we sit on the cusp of Microsoft’s next-generation Vista OS.
Anyone purchasing a notebook today should examine its capability to support
the applications and operating systems of tomorrow.”

delivers desktop-rivaling performance and a cutting-edge, multi-media

excellent solution for productivity and mobility.

The ThinkPad R51E notebook, based on ATI’s Radeon Xpress 200M chipset with
DirectX 9 integrated graphics, offers an affordable feature-rich,
entry-level business solution. With its support of the latest industry
standards and next-generation operating systems, Radeon Xpress 200M ensures
