Just wanted to chime in that you really should test ride a few different brands/styles of bike before making your choice.
I initially was thinking I wanted an Electra Townie 21D, but I tested a Specialized Ariel, then the Townie, then a Giant Roam (which makes a women's version that is step-through). I found that the Electra bike, which is made in only one size for each model, just didn't fit me as well as the other bikes. Also, we live in a pretty hilly part of the country, and I didn't get nearly the same bang for my pedaling buck on the Townie. Granted, it was a comfy ride, and I could see why if you're going to mostly ride flats in the city or at the beach and you are worried about sitting up high on a regular bike you might still get one. Just make sure you test out other bikes before making that decision.
Have fun! We've really enjoyed learning about bicycles and getting to know the folks at our LBS, as well as test riding a few different bikes.
