Time to sell Dell?

I read this morning that Dell has hired Michael Cannon, formerly of Maxtor and Solectron, as its new President of Global Operations. If you look at the histories of Maxtor and Solectron, what you'll see under Cannon's leadership is declining stock value, lost market share, and lost jobs. Cannon is, ironically, called a "turnaround specialist" by some. Of course, why someone would hire someone whose turnarounds are mostly negative puzzles me, but then again, it's not my company.
