At this time, the product does not auto-scale. The main use case is for testing sites that are using responsive design or other techniques to dynamically change their layout based on the device, or web apps using jQuery Mobile etc.

I was also wondering how accurate the Ipad simulation is. I installed the trial version and tested our design (http://www.natcheurope.com) to see if our top-menu was displayed correctly. Everything looks fine on the simulator but when I use Safari on an actual device, the padding on each menu-item appears to be too big, putting our Twitter bird on the next line. I solved it with decreasing the padding between the items from 29px to 25px (which solved the issue) but it isn't very reassuring to use Electric Plum as THE way to properly test my design.
Thanks for the feedback. We are working hard on an even higher fidelity engine for our next version, but the current one does a very good job in the majority of cases. Sometimes nuances in the typography and fonts available on the desktop can cause these pixel differences, and if they occur at a break it’s exacerbated.
In my experience there is no guarantee that emulators are 100% the same as the real device. You will often have to use other supporting test platforms, like Safari developer. The emulators are still great, particularly with the debugging features and they do help enormously. They are also good for quick demonstrations.
