Great potential if note stifled by bureaucracy; stay around for the insurance.
Pros
Resources (e.g. equipment, expertise) are widely available. The chance to make a difference in the PC industry is greater here than nearly any other place. There remain some very smart people, even though many have left either due to incompetent management or lack of ability to cut through the bureaucracy.
Cons
Intel has a simply huge extremely bloated bureaucracy. This results in the inability to make decisions -- either to try something new or to quit doing something old. As a result, it can be EXTREMELY frustrating to watch. Many groups have strongly top down management style, usually by people who often have no clue (technical or business-wise). There are a lot of old-timers who rose in the ranks either from length of being there or from having so many people hired under them. These people are usually not bright, and usually INCREDIBLY insecure, resulting in political nightmares. See the book "Losing Faith" (google it) for a good description.
