The awesomeness in my opinion is that a) this took me literally five minutes which means that I had to write absolutely none of my own CSS classes for mobile prototyping, the wonderful guys who developed Ratchet did that for me already! Also, Ratchet is not an MVC framework, it's a front-end iPhone targeted mobile prototyping framework. It allows you to prototype a mobile UI with HTML/CSS/JS faster than prototyping in native Objective-C. At first glance, I honestly think these guys are being humble by calling it a prototyping framework. I could see myself using this for mobile web versions of my apps, although that does presuppose that everything "works" pretty closely to the level one would expect it to reading the docs on their homepage. Check out the link I posted in another comment, you might be confusing Ratchet with something else.
UPDATE: This was probably really stupid of me to do right now, but I've been wanting to change my GitHub name for awhile... and just did... so if anyone would like to checkout the repo you can find it now at https://github.com/kulte/ratchet-signup
If what you mean is there a CDN for the Ratchet javascript, I don't think so. If you go to the website http://maker.github.com/ratchet/ there is a download link, but my repo just augments what you get in the download folder... like I said, 5 minutes :)
EDIT: I see what you mean now, no I didn't put up a hosted link since I just developed the one screen during a 5 min break. That's a decent idea though, maybe I'll make a full demo application (maybe I'll make it a Todo list, no one has ever used that for a demo app before) and put it up on Heroku.
Hey, that's great, but you could already do rapid app prototyping all the way to full app development with Kendo Mobile. Paired with PhoneGap it's a highly productive way to build an app.
Thanks for mentioning Kendo, hadn't heard of it, just checked it out though... kinda pricey :) I think it's pretty awesome that someone developed a free, open-source mobile UI prototyping framework.

It has a form (missing a submit button) and then an "OR, sign up with Facebook".
