Mark! how many manager's req. do you get every year? Is that 1-3. That's difficult to make a living for.
On the positives of being in the management-
1. You (really) know the future direction of the product, instead of hearing cooked direction.
2. You (really) know the product definition/architecture at higher level.
3. You can choose to do tech. work yourself and get the frills done by the team.
4. You get to see a percentage of product revenue. Your efforts directly translates into several-thousand dollars- not pennies :)
