Logitech has debuted a smaller mouse designed for portable PC users, as well as a wireless trackball, at the CeBIT show in Hanover. Executives of the peripherals company said that although Logitech is moving more into Internet oriented devices such as Web cams and hot-button keyboards, the company has no plans to ignore its main product. The new Logitech products include the Mini Wheel mouse, which is 20 percent smaller and sports a shorter cable than a standard mouse. The mouse will be available in May with either USB or PS2 connections, but the company did not disclose pricing. Logitech is also demonstrating a cordless version of its TrackMan Wheel. The cordless TrackMan, which is aimed at high-end users, has both PS2 and USB (universal serial bus) connectors and will be available in August. The company is also launching a Web site, called Spotlife.com, which is designed to allow Web cam users to post their streaming videos for public viewing. Spotlife.com is currently in preview mode and will officially launch in April, said Marcel Stolk, vice president of retail sales and marketing and general manager of Europe for Logitech. The site also has the backing of venture capital firms CMGI@ventures and Atlas Venture, Stolk added.
