So many ways to launch programs. A good launcher doesn't just launch, it also auto-completes paths for you, starts your search engine or browser and generally saves you 15 minutes a day. No need to learn all the hotkeys like those Keyboard wonks who try to guilt you. Just learn ONE and make it do everything.
Given these offerings, if you open your Start Menu at all, at any point in the day, you're doing something wrong. Try them all, pick one, and save 15 min * 5 days * 52 weeks = 65 hours a year you'd have spent futzing around in your Start Menu*.* These numbers came straight out of my butt.
UPDATE: I forgot a few that were totally worth mentioning. My bad.
