Until recently, Sun Microsystems' idea of choice was running its Unix-based Solaris operating system on any one of its Sparc-based servers. During the past few months, however, Sun has redefined its meaning of choice by promising a Linux operating system and Advanced Micro Devices Inc. x86-based servers that more accurately reflect the market's current sensibilities. Sun took its new strategy a step further Wednesday by revealing a deal with EDS to provide desktop-support services to users of Sun's Java Desktop System, which is scheduled to ship in a few weeks. Java Desktop is a key component to Sun's future. More than an open-source alternative to Windows, Java Desktop could also give interested companies reason to take another look at Sun's other hardware and software.
