I've been switching from coffee to tea as well. For one thing, tea is simpler to make. Tea bag + hot water = tea vs. getting a filter, grinding beans, waiting for the coffee machine, etc. Also, for me, drinking more than two cups of coffee/day makes me feel jittery, messes with my stomach, and pushes my caffeine tolerance up to the point where I get withdrawal headaches if I go back down. I don't have those problem with tea. I can drink multiple cups without getting the jitters.
