Manager Vs Leader - a perfectly wrong question

I see inordinate number of people asking this question, what is the different between manager and leader? I feel the question itself is wrong. Manager is yet another role like programmer, analyst , designer etc...a good manager is one who can manage assignments diligently and tactfully and has good people management skills, whereas leaders can be found in any role (not just managers), an individual who takes initiative, who inspires, who wants to challenge status quo and who wants to achieve their goals and help others achieve theirs is a leader. And that individual can be lowest in the rank of hierarchy but is still a leader. Make sense? let me know your comments on this.
