Don't feel compelled to rush into a clipless setup. Riding with platforms doesn't give you a bad image (unless you're riding with a bunch of hard-core 'racers'), make you less safe or deny you substantial power. People all over the world ride platform pedals, and have for a hundred years, for primary transportation and recreation.

Take your time and decide whats important to you. Understand YOUR needs and the pros and cons of various pedal designs. You'll figure it out in due time. Enjoy the process of learning an important facet of cycling without being unduly influenced by style considerations.
