Blurb books without Flash... only on iOS?

Blurb is a company that prints books on demand allowing consumers to self-publish. It's a great idea. Also really cool is that you can see previews of the books online. However, these previews require you to have Adobe's Flash player installed.

This wasn't that much of an issue in pre-iOS days, but since the iPhone and iPad cannot view Flash content, it's a good idea for sites to at least have a non-Flash version. Those annoying "missing plug-in" messages are bad and give consumers a terrible experience.

Well, Blurb did the right thing and you can actually see previews on an iPad, and they look beautiful.

However, it seems the non-Flash version works only if you view from an iOS browser. I don't have Flash installed in my MacBook Pro as that's the way they now ship from Apple. I need to test sites as a normal person (ie. my mom) would see them, so I decided to live without Flash and downloaded Chrome for when I need it (got the tip on Daring Fireball).

Well, visiting a Blurb book preview from Safari on my MacBook Pro gives me a dreaded "Content on this page requires a newer version of Adobe Flash Player". I just don't understand why they would do this. If they've already built a non-Flash version why not just display that if no Flash plugin is detected? Seems like a no brainer to me.
