I am a great fan of Jakob Nielsen. He always talks a great deal of sense about usability and has been around long enough to witness all of the cycles of fashion in design in user interfaces. He very kindly is making available, for zilch, a really detailed report about iPad usability.
I thought this was an interesting comment from the report.
Even though this report is free, it is still copyrighted information, so we encourage you to not distribute it on the Internet—or otherwise—but instead link to its home on our website where other readers can download it if they are interested. Please do not link directly to the PDF file, but rather follow the guideline to reduce “PDF shock” by linking to the gateway page that summarizes the report within the format of a simple Web page: http://www.nngroup.com/reports/mobile/ipad/
I have to say it is the first time that I have ever thought about “PDF shock” but I can see what he means since the document is 10 Mb+.
If getting the most out your iPad (and iPhone) applications is important then download.
