If reliability is your concern, then Microkernels are the way to go because a buggy driver (which will exist no matter how careful you are) can't take down your entire system. If reliability is that much of a concern, why isn't the system being designed in a way that makes the distinction irrelevant? about as meaningful as comparing a phillips screwdriver with a flathead. They're used for different purposes. Is this just that they work with different kinds of screws, or are there cases where it's actually preferable to use a flathead screw+screwdriver instead of Phillips (or Robertson, which for some reason we don't have around here)?
