Larrabee was a big deal years ago. The big wigs wanted to go after the high end gaming market plus parallel processing. Then, one day, all the hot air that filled the Larrabee balloon just disappeared, leaving a deflated, limp balloon. Did any upper management heads roll for that?
There are other examples of failures, misses, lack of strong leadership, and indecisiveness in how to focus limited resources in mobile which led to the departure of anand chandrasekher, who subsequently joined Qualcomm.
Then there are more recent failures like Broxton.. who pays the price for these failures and misses? Otellini? BK? - nope looks like it's SLM, FLM and downwards that ultimately feel the pain..
