Over many years, too many for me to be certain, I have been impressed with the power and usefulness of RoboForm. It has been a very looong time. I began using PC compatibles in 1983, and started with RoboForm within months of its introduction. Why then didn't I give it Five Stars? Well, the best answer is that they keep pushing out upgrades that don't accomplish much in each iteration. I would prefer meaningful upgrades on a 4-6 month basis, and far less nagging. None the less, I will continue to use RoboForm across my several PC installations. I upgrade often, and seldom completely retire a platform. RoboForm has been useful in 'keeping up' with my multiple installations.
