During his hour-plus presentation (webcast), Microsoft’s Steve Ballmer outlined seven areas “where we invest serious money.” He told Wall Streeters that Microsoft planned to engage in careful cash management; to maintain “right-size enterprise overhead”; and to put about three percent of its spending into research and incubation projects in the coming year. Ballmer emphasized that he believed “the economy will be relatively weak for a relatively long period of time” and was adjusting his investment priorities to reflect this fact, reports Mary Jo Foley.
