Stumbld upon this via Webmonkey.com (thanks Dennis!). Interesting on-line utility for testing web site display capability on the iPad. Still need to test the accuracy though.
From Webmonkey:
iPad Peek has a few limitations. There’s no touch scrolling, ads produce pop-ups, and embedded Flash videos and objects will still render inside the emulator even though the real iPad doesn’t do Flash. So, it’s basically a Webkit wrapper set to a fixed width and height. But, it does give you a pretty close approximation of how your site will look on the new shiny.
