For our American friends, here is a good article comparing a traditional IRA versus a Roth IRA.
My only criticism. The implication that it is only in your 40s and 50s that you need to focus on your retirement savings. As I think we have proved, the impact of compound returns is maximized the earlier you start saving. Perhaps if most baby boomers had begun an IRA when they were in their 20s, they would not be as concerned about retirement as they are in their 40s.
