The iPad is obviously not a Mac, but less obvious is the fact that it's not simply a scaled-up iPhone. Usability guru Jakob Nielsen has now released initial results from the Nielsen Norman Group's first iPad usability tests. Criticisms raised by the tests include inconsistent app interfaces, low discoverability of interface elements, and an over-reliance on a print metaphor. We're not surprised; the iPad's combination of a multitouch interface and large screen size make it significantly different from any previous device, and iPad developers didn't even have access to physical units for their initial designs. (Although it's too soon for a complete list of design guidelines, iPad developers would also do well to read the full 93-page PDF report, in addition to this executive summary.) follow link
Find Text Leading from Acrobat PDF
Ever have to recreate a document from an Acrobat PDF? You can find out most everything about the text by using the Object Inspector, except the leading. Well, here's a cheesy way to figure it out. Open the PDF in Illustrator (you just need one page). Release any and all clipping masks. Draw a guide at the baseline of the first line of text, and one on the line below. Now, Option-drag the first line to make a copy, and position it exactly next to the original first line at baseline. Then put a return anywhere in the copied line. Now adjust leading of the copied lines, so that the second line of copy rests on the baseline of the second line of the original. Now you know your leading.
Or you could buy expensive software to find the leading. Your choice.

Jakob Nielsen Releases First iPad Usability Test Results
I certainly could have added "Third-Party Apps" to the title and body in multiple places, but this was just a link to Jakob's report, not significant coverage of our own.
More to the point, it's absolutely essential to the iPad and other iPhone OS devices that they can run third-party apps. The iPad makes absolutely no distinction between Apple's apps and those from other developers, and 99.9% of all apps don't come from Apple (besides the fact that you can't delete Apple's apps). So to a great extent, the third-party app experience IS the overall iPad experience.
