Hybrids are OK bikes for many uses...especially around town rides, riding on bike trails, etc.
But, they are definitely slower than drop bar road bikes. If you're at all interested in speed, you'll want to look into standard road bikes at some point.
Me? I like to go fast, so no hybrids for me (though I do have in mind a project to create an "errand bike" that may end up with flat bars).
