????凯文?约翰逊

????当前职务：CEO，瞻博网络

????微软许多前高管在离开公司后都成了其他公司的领导人，约翰逊便是其中之一。五年前，约翰逊加入计算机网络设备制造商瞻博网络。上个月，他宣布将在找到继任者之后辞职。约翰逊非常熟悉微软——他曾经负责Windows和在线服务部门，这肯定要给他加分。但他能否给微软带来其所欠缺的创新呢？这个问题值得探讨。

????Kevin Johnson

????Current role: CEO, Juniper Networks

????Johnson is among a legion of former Microsoft executives who have gone to lead other companies. He joined Juniper Networks, the computer networking gear maker, five years ago. Last month, he disclosed plans to resign as soon as a replacement is found. Johnson's keen familiarity with Microsoft -- he once presided over its Windows and online services division -- is a definite plus. Whether he can breathe innovation into the company, something it sorely lacks, is an open question.
