"Being retired from Biking...isn't that kinda like being retired from recess?" Stephen Colbert asked of Lance Armstrong
It's not just arm length. It's about effective torso length, which has to do with the reach of your arms, your actual torso length, lower back flexibility, etc. A lot of long waisted people need to sit more upright for lower back comfort and even though the torso is tall, the effective reach is shorter than another person their height.
Femur length may also be a factor. A woman with longer femurs may need to sit back farther to get the proper knee position relative to the pedal axle, and thus the bars get even farther away.
The best thing is to go sit on a bunch of different bikes. Women's components like bars and saddles can be added easily to a regular bike.
If the top tube is too short, you may feel stiffness in your shoulders (you may tend to hunch the shoulders to have straighter elbows and take weight off your hands and pressure off your triceps), or you may feel that your elbows are in your lap, or that there's a hunch in your back.
Okay -- so there's no shortcut to know! That means when I'm surfing the web looking at bikes, I need to look at both until I know better what kind of bike fits me, or probably until I finally find the right bike.
Long femurs? I wonder if that's my problem. I can't sit far enough back on my current bike to be really comfortable.

You can surf the web for initial research, but please don't buy your bike on the web. A bike could look great on paper, but when you start turning the wheels, it won't be right for you.
The ONLY way you will know if a WSD or a "regular" bike is right for you is to test ride!!! Make an appointment with a shop that carries a few of the bikes that make your short list, and have them set up for you to demo (and be open to their suggestions of bikes that you didn't even consider). Don't just ride around the parking lot. Take it out for a ride. Try hills. Flats. Fast. Slow. Turns. How does it feel? Think you won't be able to tell the difference between one bike and another?? You might surprise yourself.

I was having a chat with our LBS about bike fit. He was complaining that he dislikes the label of WSD and the typical color choices of WSD bikes. Not, however, because the rare woman like me comes in and says, "No way am I buying a pink bike!!!"
His complaint is that he gets men in his shop who have short arms/torsos and fit perfectly on a WSD bike. Once or twice he got the guy to buy a neutral colored WSD model, but most men won't even consider a "girl's" bike.
Anwyay, it all comes down to fit. Your build and the build of the bike. Be open minded. Find a LBS you trust and a fitter that knows how to fit.
I definitely won't be buying another bike on the internet. The bike I have was bought that way because it is chainless and that's what my husband wanted, and so he ordered them. He said he didn't want to have to deal with chains. I guess when I get a road bike, I'll have to learn how to deal with them. Urrrrgh.
On the other hand, I love the bike I have and will continue to use it for utility cycling, which is all nearby. I don't think I'll want to put baskets and such on my road bike. Even though my funds will be limited and I won't be buying an expensive bike, I think I'll be wanting to keep the road bike as lightweight as possible.

Pooks -
Please keep in mind that not all bikes companies have a different frame for their WSD bikes in comparison to their "regular" bikes. One prime example is Giant. If you look at the actual frame measurements between their two small sizes, the frames are exactly the same. Their women's versions have smaller handlebars and different component sizes than their "regular" versions. Be careful to research frame size before settling completely on a WSD bike.
Good luck.
I'll definitely be test-riding any bike I buy and not buying until I'm certain it is a great fit. The surfing I did last night was looking at bikes in my price range, and then (okay, shoot me) colors. I figured I'd test ride the bikes that I loved the color of, just in case it actually turned out to be that great fit.
But I also know once I actually get to the bike shop, all bets are off and I will likely end up on totally different bikes. It was just a bit of "window shopping" before the serious shopping begins.
However, this test ride thing. When I test rode bikes before, nobody offered to let me go off for a few miles; it was just a matter of riding around the parking lot. Is that something they don't offer unless you ask?
And of course I don't know how to change gears or anything, so that's going to be problematical, unless I stick to the kind that are in the twist-handle. Does that make me a big weenie?
