Goodboy, while the virtues of Iridium are not significant, I have to comment on the wrong information provided in your message. First of all, at the altitude Iridium orbits, the difference in drag between Iridium and Globalstar amounts to less fuel than can be measured. Secondly, as previously discussed on this thread, Iridium carries fuel to deorbit their satellites after useful life. This fuel margin is such that the vehicles will fail for other reasons long before they ever have a fuel problem. Thirdly, the Iridium satellites were designed with minimum fuel for station keeping because they are 3-axis stabilized with momentum wheels and torque rods. This is a typical fuel efficient LEO design. Next, the buses for Iridium were designed by Lockheed Martin and as a company, they have built and launched more satellites than other manufacturer. Lastly, Motorola has published that it expects 6 satellite failures per year. If you look at the history of satellite constellations, 10% is better than average performance.

While I don't enjoy defending Iridium, I truly dislike bad information because it takes on the appearance of disinformation. Globalstar can stand on its own merits, providing bad data about Iridium doesn't help this thread.
