Widening its adoption of the Linux operating system, International Business Machines Corp. Friday said it would collaborate with Sharp Corp. of Japan on a handheld computer that runs the open source software. The handheld, aimed at corporate clients, will be launched in the middle of next year. It will be based on Sharp's Zaurus, which went on sale earlier this year and runs on Linux. The Zaurus has so far failed to catch on with consumers in a market dominated by handhelds running operating systems from Palm Inc. and Microsoft Corp. Source: Yahoo News.
