I can keep going.....
I'll just say a few cons that spring to mind, but as others have said this list isn't really worth analyzing:
1.) Boring as hell perhaps? Sit behind a desk all day? Bureaucracy like you can't believe. IDK, depends on the person I suppose.
2.) Probably quite stressful. Have to spend most of your energy convincing other people they should listen to you, rather than accomplishing anything you care about. Probably spend a tremendous amount of time traveling (only a con for some perhaps) and away from family, especially during a campaign season. If you are gunning for a big position, you are probably independently wealthy anyway. If it's a more local thing, you have no way of knowing whether or not your job will be around when the term ends.
3.) Getting solid tenure generally requires 10-15 years post-baccalaureate slave labor. Because of the amount that you will work, pay during this period will range from just a few dollars/hr as a grad student to maybe $18/hr as a post doc, and maybe $30 as an assistant professor if your lucky. Cush senior faculty positions take long work weeks well into your 50's to achieve.
4. & 5.) I honestly don't know much about these, but I imagine many commonly cited career cons could be applied: overworked, underpaid, boring desk job, too much competition for jobs, effects of the worsening economy, etc. etc.
